Oh yeah! The one that really razzed me was the FAO Slave Leia exclusive. Shelled out 70 bucks for that one and now you can get it at some TRUs for 20.
I worked in manufacturing for a while and something I realized is if you can retool a product with minimum of expense and sell it as a new product that everyone will buy into, then you're pretty much selling an item for twice the price. Believe me, the materials cost next to nothing in the quantities Hasbro buys it in. The cost is in the design, and if you already have the design, make slight modifications, crank out more product, repackage it, and voila!, people buy it all over again.
