Actually if you know where to look, there is dropshippers that work quite well all the time. On both eBay, Craiglist, uBid and direct sell.
One of them I know of is directron.com they are frankly incredible but for some reason, often items are out of stock.
Do research also on:
DH Gate (if you're buying just non branded items)
And of course one of my favorites insanewithgame.com
These are all dropshippers with various policies. I also found an unbelievable United Kingdom dropshipper who I as a business owner have a good relationship with now. No I won't tell who they are, some of us do have to protect our products you know!
Anyway just browse around, and if somebody says well the only way you can really profit is through buying entire wholesale pallets-- Don't believe them. You just find the right items at the right time, from my store alone I've profited more than $15 per item on alot of things, $45 or higher on some others, as high as $250 or $300 on high end stuff and it also increases customers who come back to buy.
Buying pallets isn't the only way, you have to judge the environment though and know your dropshippers like you know yourself that type of thing.
