As a size 36" chest I never seem to land great deals on the coats and jackets I see as there's a of people looking for the same thing, including all the skinny indie-rockers after a cheap blazer. Yes, I may be there with a minute to go as the high bidder on Â£17.85 but then the snipers come in and the not-especially-amazing item goes for Â£80+. If I was a 42" chest I reckon I could dress like a king for very little outlay from eBay.
I got a really nice vintage western-cut vintage shirt for Â£5 that everyone around me seemed to think was amazing and a cool used extra small orangy-tan leather jacket for Â£50 that everyone wanted to know about.
More generally, I've had some great steals on eBay, usually when the listing was typoed or didn't explicitly state the actual model, which puts of bidders. I got some badly listed Canon camera collection for Â£1000, kept the one lens I wanted and sold the rest individually on eBay for nearly Â£1600 with decent listings.
eBay, Freecycle, Gumtree, B&S boards - aside from discount outlet centres and sales I get most everything second hand. It's easy to live off capitalism's waste.
