I would present to the retailer that it would be safer for him to do the transaction through your company as you will act as a trustee / escrow (and of course you really need to do it - meaning you pay a deposit, pay more when you getting confirmation that the products are on the ship/airplane and then the last amount once the products have arrived at the retailer).
There are a few other options which I'd be happy to advise you on.
Good luck
