I can help you out with this, I have been selling merchant account for almost 4 years now. I can tell you exactly what NOT to put if you want to be approved. The big thing to worry about is chargebacks. You could be accepted by a high-risk processor, or even a regular processor (just hide the fact that you are selling replicas). If you start to get a lot of chargebacks your account will be shut down. Depending on how you plan to have your business set up, your best bet might be to get a regualr merchant account and just hide the fact that you are selling replicas, keep your chargebacks to a minimum and everybody is happy. Of course if your volume starts to get up there ($50,000 or more per month) you will start to be asked more questions.
You see when someone issues a chargeback and they win their dispute, that buyer has to be paid back in full for their purchase. If the merchant has alreasy withdrawn that money, it has to ome directly out of the processor's pocket (in which case the merchant would be blacklisted for life and never get another merchant account from any company).
The key thing is to be smart, if you are providing your customer with a quality product and they are happy with it, you shoudl nto have any prblems. But, for instance, if you tell your customer that what you are selling is real and charging them the full price; you WILL get chargebacks and eventually be shut down. Hope this helps you out-let me know if you ahve any more ?'s
