I am on OzBargain for obvious reasons. Picked up lots of great bargains. But starting to realise that I probably don't need all of them now. Made sense at the time though. Certainly used everything I got (except those free ebooks) so no regrets but maybe I could have done without it.
It is definitely up to us how we use or how long we use something but what makes a bargain once bought, cease to be a bargain? E.g. Buying a fantastic wireless mouse for $5 and not using it; that cool Bluetooth speaker for $15 and using it once every 3 months - great products, good price, certainly useful but not utilised.
People most likely spend more money when they're on Ozbargain than if they're not. Sure, money is being saved but in the end, it's too good to not go for the bargains than to save.
