I never said anything about Aliexpress. I am testing a product which could be shipped by Fedex but costs 20% of value of product. If product is $100 it will cost $20 top ship, if its $200 it will cost $40 to ship.
I am curious how much people pay for shipping? Is 20% of value too much? $200 product with $40 shipping fee to ship it internationally. With Amazon offering free shipping it spoiled things for many people. Customers don't realize that seller is paying for their shipping.
