spam txt message.  offering free dell laptop by visiting their website (and no doubt letting them install spyware or some crap on your computer)

I got a message from them that said "Congratulations! You've been choosen to recieve a $1,000 Wal-Mart Gift Card! Use approval code: Giveme Visit GIFT50.com 2nd reply stop"
If Wal-Mart was offering a gift card to me, I would think they would use the correct spelling of "chosen" and "receive". Just saying.

THIS IS A SCAM. This is a version of the advance-fee-for-something scam where something is a grant, loan, lottery winnings, interest rate reduction, tax reduction, gift card, refund, doggie, cruise, vacation, free gas, etc., and the advance-fee is for tax, shipping, registration, insurance, secure handling, processing, etc. They may send you a fake check, may want your credit/debit card or bank account number, or tell you to wire cash via Western Union, Moneygram, etc. They can put recurrent difficult-to-cancel monthly charges or a 1-time charge on your card or bank account, and sell account info to other criminals and you'll have to replace accounts altogether. Wired-cash is irretrievable - once it's picked up at the other end, it's untraceable and gone. If they want you to call them up for instructions, they may tell you not to discuss the wire with Western Union desk clerks but the real reason is WU clerks are familiar with these scams and will warn you not to wire the money.
