Stop buying what you already own.

WeHaveIt sits on the shops you already use — Shopee, Lazada, Amazon, FairPrice, Carousell, Shopify stores, and most other product pages — and tells you if this item is already in your home. No coupon toolbar. No AI bill. Just your household’s memory.

How it works

1. Buy something once Click We have this on the product page, or right-click any shop page and save it.
2. See it again later If you or someone in your home opens the same item, a bar appears: already bought.
3. Don’t pay twice Cables, vitamins, pans, printer ink. The boring stuff you forget you already have.

Works on most shops

Named support for the stores people actually open, plus a generic reader for Shopify, WooCommerce, and any page that looks like a product.
