I was writing this post earlier and something went terribly wrong, so if it pops up twice I'm sorry. I bought my Cube in summer of '03 when they offered it at Best Buy for $150 with Windwaker, a demo disc, and some crappy starter kit. The chick at the checkout talked me into buying a 2 year product replacement plan, saying I could bring the cube back anytime within the two years and get full money back. This weekend they put a platinum cube on sale with 2 Nintendo brand controllers and Mariokart DD boxed in for 99 bucks. I decided to see if the trade in deal would work and what do you know, they traded my cube for a voucher totalling 162.89. They didnt want the free Windwaker game that came with it or the demo or crappy controller, just the cube. So I grabbed the platinum cube deal for 99 and picked up MP2:Echoes with the extra 50 I had on the card. All in all, I got a Cube, 3 controllers (although one is crap), Zelda Windwaker, Mariokart DD, Metroid Prime 2, and a demo disc for a hundred and fifty bucks. I would suggest that anything you ever have to buy from Best Buy again that you know will eventually have a significant price drop, get that dang 2 year replacement plan. Well worth it. Try it out.
Here's the 10 second summary for those who don't wanna read the crap: Best Buy+2 Yr. Replacement plan= way to screw the system.
