Just don’t buy anything of value. I thought I’d save $30 buying a mtb dropper post direct from aliexpress instead of resellers on amazon. Fedex delivered it to the wrong address and the seller refused to file a claim with fedex and I couldn’t because I was receiving not shipping. Customer support sided with the seller because the label was marked ‘delivered’ and I was out $70.
Which still makes it an aliexpress issue when they choose the carrier not you.
