Hi onlinebusiness1,
I know it's been months, but I'm happy to give you some suggestions if you still need them.
eBay has become an extremely competitive marketplace and it is not uncommon to find products selling at prices the same as or lower than wholesale. There is more competition than ever, and the truth is it's not as easy to make money as it used to be.
If your feedback isn't skyhigh, then work on it. eBay buries sellers with low feedback ratings in the search listings, so less people are going to see your items for sale. The best way to get your feedback up fast? List as many items as you can and consider having a sale (either reducing the item price or offering free shipping). Even if you lose a bit of money now, you'll reap the benefits in the long term when your feedback is higher and your listings more visible.
You can also buy liquidation as it allows you to offer great prices on brand name and designer items, while still making a good margin.
