AliExpress is losing money on such sales. But why bother, then? It has to be this. I work at an E-commerce company. We often do the math on just exactly which items make a profit for us vs which don't. It's not always obvious until you really dig into the exact costs of handling the items. I believe Alibaba has a lot of 3rd party resellers, it's possible they haven't done the math themselves.
