Trawl through and get some great bargains and then resell at a higher price. I buy loads of great jewellery from China or the States for �1 or less and sell it for much more.
Or go to the multibuy section on Ebay and buy lots and sell individually
my brother and sister in law have set up their own jewellrey business and they are selling it thru ebay and making a packet....just go online to jewellrey/ whatever product you want to sell and buy in bulk, mark it up by 3 and hey presto!!
