Government liquidations, liquidations in general (govliquidation.com, liquidation.com)
Wholesale districts (I'm not sure where to find these in the UK, but over here in southern California, downtown Los Angeles has a huge district solely for wholesale)
Trade shows (Again don't know where to find these in the UK, but in the US Los Angeles and Las Vegas have huge trade shows where you can shop around)
Where I started: hollywoodbodyjewelry.com
DHgate, Alibaba, Tradekey, etc. (Don't be confused with these sites as providing only counterfeit merchandise, they have a HUGE amount of items worth selling that are non-branded and potentially very profitable or you could just sell the replicas they do offer if you've got the balls)
Flea markets, Swap meets (If you've got a good eye for deals, than you could buy a bunch of stuff at these places and make a good profit, buy low+sell high, my niche with these places were old records and antique cameras, I found a Leica camera at a swap meet once bought it for $45 resold it for $150)
That should be a good start, Google is you're friend there are plenty of other options.
