If we want to keep it general ... the things that sell well on ebay are gonna be anything that sell over and over again without much trouble. If you can list an item and sell it within the first or second try...and do that over and over again ... then I'd say "hey.... that sells well on ebay! " haha
But... I doubt that's what people really are asking.
I think what they really mean, is what can I get a hold of that's easy to get, doesn't put me at risk, sells like crazy, and will make me fast easy money ... plus I won't feel like a creep selling it... Right?
Well... then I DO have an answer for you!
Some of the best products to sell on ebay are gonna be the ones that are sort of "under the radar", aren't listed on the front page of the ebay "pulse" ... and most people would never in a million years guess would sell so well.
That's easy money if you ask me! If you can find a few items that a HUGE crowd of people GOTTA have and are having trouble getting for whatever reasons ... and then list them on ebay for a great deal ... well, you have some hot selling items on ebay that not many people are gonna catch on to.
That's what I focus on. Help out DESPERATE people that gotta have something, and get it to them for a great deal. It's the fastest, easiest money I've made on ebay so far. And it feels GREAT helping them out!
That's what sells well on ebay! Give it a try. I'll show ya how to look for these kinda items on my site listed above.
