There are quality programs out there
Regarding the doba reference I would not use them at all. You can learn enough about them on ripoffreport and other sites. I am sure they have some great tools, but there are no a dropship program. They mark up the prices from the suppliers by 2 to 6 % and some products have a markup on shipping and the dropship fee. Moteng is one of their electronics suppliers.Vertex is the bed and bath supplier. and the others are easy to spot as well. Some of there "suppliers" are listed with dropship fees but the real supplier does not have one or they list the fee at a dollar over the real supplier fee.
Depending on how many products you sell....you can run the numbers and see how much you are REALLY paying for the "service"
A dropship program will have some markup, but the idea is they sell in huge vol so the markup is small. If they get it right from the product maker, then there should be room for you to sell and profit. Now, if you use a "dropship" program who pretends to be a supplier or who gets the products from other dropship programs, etc.....then that just cuts into your PM.
