My wife shops on Temu regularly. She doesn’t trust them, so she uses one-time cards. Most of what she buys are single-use items: party accessories, crafts for kids, etc. The exceptions were solar lights, which are surprisingly durable, vastly outlasting those we got locally or Amazon. Speaking of Amazon, we used to shop there a lot but almost completely stopped. 90% of goods are just rebranded Temu products, and the “premium” selection can be found cheaper in the nanufacturers’ or speciality stores. Amazon is currently positioned very poorly, with competition pressuring them both from top end and junk. Looks like Amazon as a retailer is heading back to its origin, with books being the only reasonable deal there.
Freezer bags, 4 slices per bag, in a freezer. That way I can take out only as much bread as I can eat before it gets moldy.
