How we picked this

★ Editor’s pickNot a taste award: it meets all four published conditions — in stock, price verified against the store, a rating or first-hand use behind it, and not the priciest way to get the same thing.

• Chosen by a person, not an algorithm — it’s in this storefront because the creator put it there.
• The creator selected this item but hasn't used it — nobody here has tested it.
• We don’t lab-test anything. What we do have is our own price checks over time, our own click counts, the store’s published rating, and the creator’s own words.
• Price, availability, and the store rating come straight from theinkeylist.com — last checked Jul 29.
• Price history is our own record of every check we’ve run.
• Prices are re-checked automatically once a day, so a figure here can be up to 24 hours behind the store.
• Alternatives are ranked by observable facts: category, price distance, product type in the name, same store. We don’t compare fabric or fit — we don’t have that data.
• The star rating is the store’s own, not ours — we never score products ourselves.

Commissions never change the ranking. Store links are affiliate links and Avahit may earn a commission if you buy. That commission is paid by the store out of its own margin — it never adds to your price, and no store can pay to rank higher here. Full picking and ranking rules.
