I received a text from this number on 8/21/12.  It's suspect because I have not entered any Best Buy contest, the message came through at 4 am, and the information was vague.  Message said to go to BestBuyPrizes.Net.  I would be careful of this number, and avoid this website and any information they request.

I received a test from this number on 10/21/12 and the message said to go to bestbuy prizes.net and enter code 4787 to claim your free $1000 Best Buy.com Gift Card within 24 hours.  

When I went to the site it looked like a legit Best Buy site but instantly started a countdown starting at 4 minutes and 59 seconds AS IF the clock had been runnning JUST FOR ME and my 24 hours were almost up and I had to act.  It also stated that if you enter, you had accepted Best Buy's Privacy Policies, and no doubt, if I had entered the site would then have asked me for privacy info.   SCAM!!!!!

I didn't enter any contest but I did have the Geek Squad out to my house legitimately just last week.  I assume that scammers are somehow monitoring the phone or email traffic relating to that transaction.
