* LeSportSac got greedy and started reissuing "limited collection" bags. Which made the hunt less fun.
* Counterfeiters got better and better with the fakes.
* I had a major life style change which severly curtailed the amount of disposable income I had to play with.
Still love the bags I have though. Occasionally I'll find something somewhere and snap it up. Most recently got a computer sleeve. Not LeSportSac but still Tokidoki. And a friend bought me a Tokidoki/Hello Kitty iPad case for Christmas last year!
