I would tend to agree with Anton.
I _DO_ have some experience with drop shipping in the US. I have worked with several drop shippers over the years, one of which I was a shareholder in. It was hunting/fishing/outdoor & clothing store. It failed, though that was as much caused by the primary founder (and ceo) as it was anything else.
The biggest issue: The margins the distributors give you are just too small until you are large enough to actually make a difference. Check your disty's pricing vs, say, Amazon. You may find your margins are so slim, it isn't worth it.... unless your VALUE proposition is so good - either because you are fitting a niche or providing a product they can't get elsewhere, etc - that customers will pay an extra few dollars to do business with you. That's REALLY tough.
The second biggest issue: returns. They will PLAGUE you. Your distributor will probably not want to deal with them directly - they will expect YOU to handle that. You will then have to sort through them, decide which ones you can return to the disty as new and which you have to keep and try to sell at a discount later. Unfortunately, in the mean time, you have to eat that cash. Oh, and the shipping, because your customers will likely expect you to eat the return shipping...
Third issue: Credit Card Discount Fees - this really ties in to #1, because the margins are so small, but discount fees hit you when you get money, and they may hit you again when you issue a refund. They will get their money "coming and going," so you have to have enough markup to cover all of it.
Despite all of this, is it doable? YES
Just make sure you have an EXCELLENT value proposition for your customers.... niche, something else spectacular, etc.
Without a compelling value proposition, I'd say "NO not worth it, your ROI just won't be there."
