Your opinion, please

So, when I bought my awesome 55" HDTV last month, I signed up with Best Buy's Reward Zone program. You get points for every dollar you spend, so you can get usually $20-50 in gift certificates based on what you spend.

Thanks to a huge promotion at Best Buy when I signed up, I got an ungodly amount of rewards points, and just received $520 in Best Buy gift certificates that I now have to use.

I need suggestions!

What would you get if you had $500 to spend frivolously on anything at Best Buy?
