Sales are always a good excuse to exercise your credit card, so the IWantOneOfThose.com sale is proving to be rather tempting for me!
If you want to get into Podcasting (something I've been threatening to do for ages!) then the Behringer USB Podcast kit is a pretty good deal. I picked one up last year and it gives you everything you need to get started at a reasonable price.
Of course podcasting might not be everyone's cup of tea, so how about gnome bowling?
I've always hated garden gnomes, so I'd get satisfaction from hitting them with a bowling ball. Wouldn't you?
But whatever you do, please don't buy the finger drums - your office colleagues won't thank you!
