The parent company for AliExpress (Alibaba) has posted record profit (over 300billions). AliExpress has the cash to reimburse me.
AliExpress is an international sales platform. I think they really want to demonstrate that it is a safe marketplace. If I were to lose $175 on this transaction, I won't be back to buy any big ticket items, and their profit has some % of sale price dependence.
Ebay and Amazon deal with bad vendors swiftly, and it only HELPS their bottom line. Customer confidence is top priority.
I got a set of rubber floor mats on Amazon recently. The rear set didn't fit. I documented the bad fit (photos). I got a refund announcement the moment that UPS recorded the return package I took to the UPS drop off. Amazon didn't even wait to inspect the package contents! And I didn't even have to deal with a shipping label- it was a UPC code square on my phone scanned by the UPS dude. Will I confidently buy things on Amazon? You bet
