I just got a text today from this number.  It's from best buy.  Don't know how they got my cell # when I don't shop there and I don't give out my cell number, I've had the same number for 11years and never had this happen.  The message reads as follows  "Best Buy $1000 Gift card for the first 1000 users to go to http://Best-Buy-Offer.com and enter code 1837"
