Hey connor,
Yeah there is no reason why you cant sell via dropshipping companys in usa,to usa customers, as long as you are positive that you have chosen a reliable company.
There are obviouslly going to be more complications though, and I think you could be just as successfull selling in the UK through UK dropshipping companies. (although there is rarely a very large profit margin when dealing with dropshipping companies).
You might also find that the profit margins you have from dropshipping companies are not large enough to cover the costs and fee's incurred through selling on ebay!
Bear this in mind, and be sure to fully understand exactly what profits can be made on the items your selling after any incurred costs! Common sense really!
Hope this helps.
