The main places to find canning supplies

You can buy canning supplies at grocery stores, hardware stores, online retailers, and specialty kitchen shops. The best choice depends on what you need, whether you want to see items in person, and how quickly you need them. Most people find what they're looking for at one of four types of retailers.

Grocery stores carry the basics year-round: mason jars, lids, pectin, and pickling spices. Larger chains like Kroger, Safeway, and Whole Foods stock these items in their canning or baking aisles. During canning season (late spring through early fall), selection expands. Smaller local groceries may have limited stock, so call ahead if you need something specific.

Hardware stores like Home Depot and Lowe's sell larger equipment: pressure canners, water bath canners, canning racks, and bulk jars. They also carry specialty items like jar lifters and bubble removers. These stores typically have good selection during summer months but may stock less in winter.

Key Takeaways

  • Grocery stores stock mason jars, lids, and seasonings year-round in the baking or canning aisle, with expanded selection during summer months.
  • Hardware stores carry larger equipment like pressure canners and water bath canners, plus specialty tools like jar lifters and bubble removers.
  • Online retailers like Amazon and specialty sites offer the widest selection and ship directly to your home, though you cannot inspect items before purchase.
  • Local farm supply stores and farmers markets often have bulk jars, pectin, and produce-specific supplies at competitive prices.
  • Restaurant supply stores sell commercial-grade jars and equipment at lower per-unit costs if you buy in quantity.

Online retailers and what they stock

Online shopping gives you access to brands and sizes that local stores may not carry. Amazon stocks everything from basic jar sets to specialty equipment, with fast shipping in most areas. Specialty sites like Lehman's, Ace Canning, and The Canning Bug focus entirely on canning supplies and often have detailed product descriptions and customer reviews from other canners.

Ball and Kerr, the two largest jar manufacturers, sell directly through their websites and through retailers like Walmart and Target. Buying directly from the manufacturer sometimes means lower prices on bulk orders. Shipping costs can add up for heavy items like canners, so compare the total cost including delivery before ordering.

One drawback to online shopping: you cannot inspect jars for chips or cracks before they arrive. Read return policies carefully, especially for glass items. Most retailers will replace damaged jars if you report the problem within a few days of delivery.

Local farm supply and specialty stores

Farm supply stores like Tractor Supply and local agricultural co-ops carry canning supplies alongside gardening and food preservation equipment. These stores often stock bulk quantities of jars at lower per-unit prices than grocery stores, which makes them worth visiting if you plan to can large batches. They also carry less common items like specialized pectin for low-sugar recipes and bulk spices.

Farmers markets sometimes have vendors selling canning supplies, particularly during peak season. Prices vary, but you can inspect items in person and ask the vendor questions about their products. Some markets also have local producers selling homemade pectin or specialty seasonings.

Restaurant supply stores open to the public (like Restaurant Depot or local equivalents) sell commercial-grade mason jars and canning equipment at wholesale prices. You typically need a membership, but the cost savings on large orders can pay for membership quickly if you can regularly.

What to expect to pay for common items

Mason jar prices vary by size, material, and where you buy them. A dozen quart-sized jars typically cost between $8 and $15 at grocery stores, less at farm supply stores if you buy in bulk. Pint jars and half-pint jars cost slightly less per dozen. Specialty jars like wide-mouth or decorative styles cost more.

Lids and bands are sold separately. A box of 12 lids costs $3 to $5 depending on the brand and where you shop. Bands are reusable, so you buy them once; a dozen bands cost $2 to $4. Replacement lids are cheaper than replacement jars, so many canners buy new lids each season and reuse jars for years.

Equipment prices range widely. A water bath canner costs $25 to $50. A pressure canner (needed for low-acid foods) costs $75 to $300 depending on size and features. Specialty tools like jar lifters, bubble removers, and headspace measuring tools cost $2 to $8 each, or you can buy a complete tool set for $15 to $25.

Seasonal timing and stock availability

Canning supplies are easiest to find from May through September, when demand peaks. Stores stock more varieties, prices are competitive, and selection is widest. If you wait until October or later, many retailers reduce their canning sections and may run out of popular items like pectin or specific jar sizes.

If you can during off-season months, order online or plan ahead. Some items like lids and pectin sell out quickly in summer, so buying in advance prevents frustration. Jars are generally available year-round, though specialty sizes may require ordering.

Check store websites or call ahead during peak season to confirm stock before making a trip. Many retailers update inventory online, which saves time if you need something specific.

Comparing prices across retailers

Prices for the same item can differ significantly between stores. A dozen Ball quart jars might cost $12 at a grocery store, $10 at a hardware store, and $8 at a farm supply store buying in bulk. Shipping costs change the math for online orders, especially for heavy items like canners.

Create a list of what you need, then check prices at two or three local stores and one online option. Factor in shipping time—if you need supplies this week, paying more locally may be worth it. If you have time to wait, online shopping often saves money despite shipping costs.

Buying in bulk at farm supply stores or restaurant supply stores makes sense if you can regularly or preserve large quantities. Buying a single dozen jars at a grocery store makes sense if you're trying canning for the first time and want to start small.

What to look for when buying used equipment

Used canners, jars, and tools are sometimes available at thrift stores, estate sales, and online marketplaces like Facebook Marketplace or Craigslist. Used jars are fine if they have no chips or cracks. Inspect the rim carefully—a damaged rim will not seal properly.

Used canners require more caution. Pressure canners have a pressure gauge that can wear out or become inaccurate over time. If you buy a used pressure canner, have the gauge tested by your local extension office before using it; an inaccurate gauge is a food safety risk. Water bath canners are simpler and safer to buy used, as long as they have no rust or holes.

New equipment is safer if you are unsure about the history of a used item. The cost difference between new and used is often small enough that buying new gives you peace of mind and a warranty.

Frequently Asked Questions

Can I use any jar for canning, or do I need special mason jars?

You need jars designed for canning—specifically mason jars or similar jars with a threaded rim that accepts standard canning lids. Regular drinking glasses and food storage containers do not seal properly and are not safe for canning. Mason jars are inexpensive and widely available, so there is no reason to use anything else.

Do I need to buy new lids every time I can?

Yes, lids should be replaced with new ones each time you can. The sealing compound on the lid works only once. Bands (the metal rings) are reusable for years. Jars themselves are reusable indefinitely if they stay undamaged.

What is the difference between a water bath canner and a pressure canner?

A water bath canner is a large pot that boils jars in water; it works for high-acid foods like jams and pickles. A pressure canner heats jars under pressure to reach higher temperatures; it is required for low-acid foods like vegetables and meats to prevent botulism. You may need both depending on what you plan to preserve.

Is it cheaper to buy canning supplies online or in stores?

It depends on what you are buying and where you live. Grocery stores are convenient for small quantities of jars and lids. Farm supply stores offer better per-unit prices on bulk orders. Online retailers have the widest selection but add shipping costs. Compare total cost including delivery before deciding.

Where can I find specialty items like low-sugar pectin or unusual jar sizes?

Specialty canning websites like Lehman's and The Canning Bug stock items that local stores may not carry. Farm supply stores sometimes have low-sugar or no-sugar pectin. If you cannot find something locally, ordering online is usually your best option, though it requires planning ahead for delivery time.
