Selling from the UK - how do I make a profit?

Hi my name is Steve and as you can probably guess I live in the UK. I am trying to start my own business but everything I find to sell on e-bay is selling for roughly the same price as what I will pay with a wholesaler, so how will I ever make profit?. I might as well put my customers in contact with the companys I buy from. Someone please help me?.

You just have to keep searching. You will be able to pay less if you buy more as well.

I'm having much the same problem. I made more money selling my husband's old camera lenses and my daughter's 'gently used' Coach bags than the potential profit that most of the wholesalers offer.
Finding a specialty such as estate sales seems to be the key. And even there, isn't everyone else looking for just as much of a bargain as you are?
Can't figure it out.
