I am trying to understand these different terminologies. Let's say I buy an xbox controller from newegg and resell it in my store at 15% markup. A customer places on order on my site, I go to newegg and place their order and have the shipping address my customer's address. Is that considered dropshipping, even though I am not buying from a whoelsaler? What is the difference between reselling from a wholesaler, and reselling from another retailer?
