Wish is far from the everything store. It takes a gimmicky approach to commerce, trying to make consumers feel special through psychological tricks. The products it sells also seem untested and suspect — cheap, but potentially not even worth the low prices they're being sold for.
To shop on the site is to experience a strangely persistent gamification, involving sifting through mountains of stuff to find something that may or may not appear as good as it did in the photos when it arrives in a month.
Still, the low prices and low shipping fees are a major draw. Shoppers do love low prices.
