After about 15 orders from Aliexpress, I can determine that Aliexpress is too expensive:
1) I have multiple shipping addresses, and always keep getting the shipment to the wrong address that require extra shipping costs to the right address.
2) When ordering clothing, out of the 3 orders I made, two were the wrong size. Shipping back is prohibitive, so the unfit clothing went straight to the Salvation Army.
3) Quality. In three cases quality was so bad and the products were used for very short time before being filed in the garbage.
