I've ordered things from TEMU and AlliExpress. $2 to $10 items from TEMU. Shipping is not like what we're used to from Amazon. 2-3 weeks seems typical, but to be fair, I've had things from Amazon take over a week (and seemed like they got fulfilled from china too). Clothes are terrible because they follow Chinese sizing, so 1XL or 2XL is the equivalent of a Medium in the US, and larger sizes have poor availability.

I find it hard to say they are taking DG's market share away. The DG's in my area carry lots of food - not something I'd ever get from the likes of TEMU or AlliExpress, and they carry in-season merchandise that you really have to plan ahead of time to get from TEMU. (ex. Christmas decorating - order during Halloween, sand castle building kit - order 4 weeks before your vacation).

But both these Chinese apps have so many categories of merchandise that the dollar stores don't carry that I'd be wary of saying their success or growth means dollar stores are doing poorly.
