do you think dropship sales is good ?

Drop shipping is where you order from a third party, rather than having the item in your possession, first before shipping it to a buyer. For example, I am an artist who also makes copies of my work through another producer. I can list the product for sale and then order it through the other producer to be shipped directly to the buyer instead of ordering it to be sent to me, first. It saves money by not double-shipping and not producing items unless ordered. I think eBay allows that, but some other sites don't.
