Your distributing, its all pretty simple buy low and sell high. that said you need to evaluate each step of the process to determine what yields the highest ROI for you. Buying from the large warehouse certainly has a lot of advantages but you can expect to pay for those advantages, so part of the questions become is can you do it cheaper (increasing your ROI) and what impact and costs would be involved with maintaining your own inventory. Having owned a business with and inventory in excess of 20,000 items I can tell you hat inventory can very quickly become a dirty word.
Personally unless there were significant profit in touching the inventory directly i would be happy to have someone else responsible for the inventory, shipping, and the staff involved with all of that.
