Plenty, though I'm not sure the total. But what I spend is within my budget, so it's all good.
Some folks look aghast when I say I spend money for items in a virtual social network world. But then they get it when I point out that they think nothing of spending money to attend a concert, movie or sporting event - entertainment that last but a few hours and for which they have nothing but memories & perhaps a program and/or ticket stub to take away. At least I can repeatedly enjoy much of my virtual stuff.
About $50 probably, and yes I regret half of it. Most of the clothing I don't even use anymore, best spent money has been anything on a game within Home. I've heard of people who have spent above $400 in Home, which sounds extreme considering what Home is,. But hey, if people like paying for it and that's what makes them happy...

My guess is over 700-800$, over 4 years span. However, I'm sure my friends would insist it's way more! Quite honestly I don't want to know. I'm worried it's over $1000. O_O OMG that's scary when I think about it! LOL!
