ebay's got considerably easier to use over the years, plus I get 20 free listings a month, so there's no excuse not to shift some stuff.
Anything that doesn't sell can always get bagged up for the charity shop, but I've deliberately kept prices low to tempt the bargain hunting crowd.
If I you will indulge me with a shameless plug, I'm at
If you've never got to grips with ebay I'd heartily suggest you have a go. It's not tricky, and it's a safe way of selling and buying. If you can't face it, but also quiver at the thought of a car boot sale (or don't have a car!) then look out for table top sales. These are often advertised in local free newspapers or on notice boards outside churches. Some concentrate on selling handmade craft items, but plenty would welcome a good old fashioned White Elephant stall of bric a brac. You'd pay a few quid for having a stall, but you're bound to make that back in sales.
Alternatively, have an American style garage or yard sale with a clothes rail and a table outside the house piled high with unwanted household clutter. Finally, there's always Trade-It. I picked that up the other day and was staggered to see what was being sold. My dubious sounding favourite was a woman selling an Ann Summers bra and knickers set for £2.00. Un-used, she assured the reader. Phew! That's a relief.
