(For what it's worth, I used to interact a lot with similar businesses when I was working for eBay plus I am currently running my own similar business). Here are some tips: 1. Keep your costs very low while you are figuring out if there is a market. If possible, use sites like shopify, eBay, Amazon, etc to find some first buyers for minimal web development and only order a relatively small amount of inventory - hopefully you won't end up with a pile of un-saleable inventory while working out if this can sell. 2. If you can source the inventory cheaper than is the current market price, that can be a good advantage - but don't think that cost will be your only advantage without worrying about marketing etc. 3. When calculating your sale price, factor in fraud, refunds, wastage, etc. Regarding fraud, it seems like a regular occurence - be hesitant shipping large orders to unknown customers with unverifiable addresses. Hope that helps.
