First off, Google has this new app called Google Wallet which is exclusive to Sprint, specifically on their Nexus S 4G, a phone I recently got. Google Wallet makes it so your phone acts like a payment device, similar to Paypass which is a little device in your debit/credit card so you could just tap a console to pay. Since I set up my phone with Google Wallet, I got $10 in credit.
Now this week, CVS has this little deal on their site where if you pledge not to be a "Money Trasher" and have a CVS card, you can get $2 in printable Extrabucks. They also have a deal now where if you purchase $10 worth of Physicians Formula products, you get $7 in Extrabucks.
I used the $10 credit from Google Wallet to purchase the Physicians Formula Gel Cream Liners which retailed for $10.99 and paid $1.84 up front and received $7 Extrabucks. I then purchased the Mineral Wear Correcting Primer for $10.99, used the $2 Extrabucks coupon in addition to the $7 Extrabucks I just got and paid $2.69. The primer has the little "Try It Free" sticker on it for the rebate.
I'm not sure if I will get the full retail price of the primer back but either way, paying about $5 for over $20 of product is always nice yeah?
Take advantage of the CVS moneytrashers deal while you can, I believe it expires on the 2nd or 3rd.
