It would be better to ask this question on the sellers board.
However, you may find that sellers will be a bit coy about sharing information on where they source their stock!
Keep in mind that if you are buying to sell on eBay you will need to upgrade your membership to a business seller. Private sellers are restricted to selling their own, unwanted possessions.
Good luck. You might want to keep an eye on this forum, where you could learn from the experience of other sellers who come here with their problems.
