The S1 talks a lot about their logistics platform and diversifying their merchant base to come from different countries, instead of just China - and rightfully so, since until July Wish’s business was subsidized by the Universal Postal Union treaty. Thanks to the UPU, Before July it was cheaper to mail a package to Chicago from Shanghai than to shop to Chicago from Dallas.
