Hi findithere, nice to have you with us.
You're right of course, that's one of the most popular questions around, what to sell?
One of the absolute best tips I can give you is that what is hot, may well be not what you want, especially if ebay is your marketplace and especially of Drop Shipping is your supply method!
Hard to compete on ebay in most categories, but the hottest selling item genres are usually swarming with very well resourced sellers, making it near impossible to get into them at all.
Key word in a business like ours is research. you can never do too much of it and when you think you've done enough, that's when it's time to start doing more lol.
It never ends!
