These are indicative budget bands, not quotes, converted near-par (1 USD treated as 1 GBP) rather than at an FX rate: US retail prices exclude sales tax and UK retail prices include 20 percent VAT, so near-par plus rounding to a natural price point stands in for that gap. Converted 2026-07-30. The pressure canner and dehydrator named above carry the same import-only caveat as B3.
