Yes, it does. But this problem has nothing to do with that. This problem is a seller massively increasing the price of a product from $10 to $22-25. So he needs to find another seller with a cheaper product.Doesn't Alidropship plugin do automated price synchronisation?
You can't pay later. The order can't be processed until you pay.place order with supplier, but choose to pay later, then negotiate price. Instead of losing business supplier will adjust the price!
