Well to be honest I've not really made any 'extravagent' purchases at all lately...
The last was probably my PC; but that's only really used for ASN, E-Mail, downloads and as a big Haynes Manual / Parts Catalogue for the cars (although I did used to game a bit...)
...Spending lately has been on essentials. I've put about £4,000 worth of Diesel in the car for personal mileage, a few quid on maintenance (given that it's done 6 years distance in less than one) etc.
I bought an engagement ring which I guess sits between extravagent and essential - extravagent because it was a big thing that I'd never done before, but essential because it's required if you want to get engaged!
I think maybe the last thing I spent money on was a little extravagent, or perhaps it was just overpriced... £200 for the train ticket to London I'm currently using!
