- When does Kerr go on sale?
- Kerr jars are discounted most often during late-summer canning season and around Black Friday, when big-box retailers and farm stores clear cases. No Kerr deal is live on this page right now.
- Where is Kerr cheapest?
- Case prices are usually lowest at warehouse clubs and farm-supply chains, and per-jar cost drops as case size grows. Compare the price per jar, not the case price, since case counts differ by retailer.
- What are Kerr's best products?
- The two-piece mason jars with lids and bands are the core line: wide mouth for whole fruit and easy filling, regular mouth for jams and sauces. Both are tempered glass and safe for water-bath canning.
- What is Kerr's return policy?
- Returns are handled by the retailer that sold the jars, not by Kerr, so the store's policy and receipt govern refunds. Check jars for chips or cracks before use, since damaged glass is usually replaced by the store.
