I happen to like the thumb drives that Lexar (Crucial / Micron) puts out. They were the first company to offer a rebate through Staples and since I'm married and on a budget, I got a deal that I could afford while all the other manufacturers were more high priced. If you noticed, Sandisk has more of a monopoly of the retail store outlet because Bestbuy, Circuit City and other stores are selling Sandisk's products big time while a company like Lexar (Crucial) is not doing as well and you can probably find some of their products in Target or Office Max.
These companies buy the wafers from another company which sells the product at the same price to everybody so if you expect to show price fixing, you have to remember that the market is very competitive and Toshiba and one other company created this kind of hardware so you can are basically paying Toshiba and another company the royalties so if you are going to claim "price fixing", you need to have more proof because a buyer from one retailer is going to say,"Can I get this product at a more competitive price?" and they are all getting the wafers from some of the same sources at the same cost. And salesmen don't give deals but offer everyone the same price because they play a price game and you never see their price for anything.
If you are complaining about buying thumb drives at the same price then it is your responsibility to get a better deal. I recently bought a flash card made by Transcend and it was cheaper buying it online than buying it from Circuit City or Best Buy because you are paying for the store's rent. If you want to sue someone, I suggest that you sue the local malls here who believe the average family income is $90,000 and we pay an average of $119 on the average shopping trip because all the malls around here are owned by the same reality company and I have to shop at Target, K-Mart or Wallmart, (sometimes Sears) because the mall is generally too expensive because they have their hand in the pocket of the retailers they rent to. If you open late, close late or don't open, you get fined by the mall. When it is holiday time, they pay double rent and it the bills we pay is based on what they think we make.
