My case is a necklace order.
My customer chose Epacket for shipping.
They have to pay 10 times for shipping orders of 10 pieces.
But when I order at Aliexpress. I only have to pay 1 shipping price for this necklace order in quantity 10.
Sorry for my bad English: D
I have disabled: Original images backup
I set the server to upload a representative image and product variation image.
For example: A product I imported has 1 avatar image, and 4 images of the product variant. When finished product import. I get 10 images on the server.
I found the cause. If edited directly on the site aliexpress.com will not be able to automatically update prices for variants. Only import it can do this.
