Ok, I did 2 test orders - both to my home. It was only going to be one but since some products were cancelled (and credited) from the 1st order, I just added a little to the credit and placed a 2nd order.
I have to say that there is no acceptable way that I could use them as a drop-shipper and it's not just about the time it takes to ship from China to the US. What I found amazing (and completely unacceptable) was that it took 6 full days from the time I placed my order to be shipped out! On the first order, I chatted with support on the 4th day, asking why it was 'being prepared' for so long after I paid instantly - and that a delay like that would not be good if I was drop-shipping. They said that it would ship that day (it didn't) and that in the future, if I was ordering for a customer, I should call or chat to expedite the order. I purposely did not call or chat on the 2nd order to see how long it would take to ship - 6 days again.
1) Having items that are ordered and paid for and then cancelled because they are not currently available - this alone would prevent being able to order for drop-shipping because I couldn't be sure that the product would actually ship. If it's not currently available, then it should listed that way, not paid and then 6 days later it suddenly credits the balance and doesn't ship with the rest of the order.
2) There is no reason for an order to sit in 'preparing' for 6 days - period. The fact that it took 6 days with both orders tells me that this must be typical. - Unacceptable.
3) I shouldn't have to call or chat to expedite an order for a customer - orders that are paid for should be shipped.
4) The time it takes to get to me once it ships can't be avoided (about 2 weeks).
Because an order takes so long to get from China to the US and then shipped from the point of entry to us, you'd figure that they would ensure they pumped the orders out quickly... sadly, that's not the case.
