DSers‑AliExpress Dropshipping

Dsers Supplier Optimizer is attempting to only show their Tmall items. These items say "Only available on Tmall" but when I do my own search on AliExpress, there are plenty of suppliers with the same item that I tried to find using Supplier Optimizer. Tmall items are more expensive and delivery times are longer. I don't want to source from Tmall and not accurately showing what's available on AliExpress feels very suspicious. I will cancel my subscription and find another way to import AliExpress items. I don't trust that Dsers is being honest about what's available on AliExpress but pushing its own brand in a deceptive way.
