Don't get me started on those chips and tazos! With 3 kids collecting and trading I am sick of the sight of them :rant
And yes you can buy them online, but the whole fun for kids (well maybe not you big kids) is collecting and trading.
A friend of mine bought the set on Ebay for $50 for their kid - the whole 72 tazos. Kinda takes the fun out of it for the kids and its not like they will be worth anything in years to come, they bring out a new set every bloody year. Most of 2007 set are laying around my house under lounges and beds!!!
