CVS Spend $30 Get $10 in Gas!

WAHOO!  CVS just made an exciting announcement! As if their sales/rewards weren't good enough, now they're also going to be giving out FREE GAS CARDS! Here is the announcement:

"With summer around the corner and gas prices reaching $4 per-gallon nationally,CVS/pharmacy has announced a new program designed to allow customers to earn free gas all summer just by shopping for essentials at more than 7,200 locations nationwide. From May 22 - August 28, 2011, members of CVS/pharmacy's ExtraCare Rewards program can earn one $10 gift card to Exxon/Mobil, Shell, BP Amoco or BP Arco every week simply by spending $30 on specially-marked items found conveniently in the weekly CVS/pharmacy circular.


Participation is easy. Customers can find the qualifying products on the front and back pages of the weekly CVS/pharmacy circular beginning May 22, accessible in-store, online at http://www.cvs.com/ and on Facebook at http://www.facebook.com/CVS. All qualifying products will be tagged with a "get free gas" icon to make them easily identifiable. Eligible products will rotate each week, giving shoppers greater flexibility to fill their carts with the essentials they shop for each week.


Once ExtraCare customers reach the $30 required purchase threshold, a special coupon will print on their receipt that can be redeemed immediately in store for a $10 gas card. If customers prefer to wait to redeem their coupon they have up to 30 days to do so. Limit one redemption per week for each ExtraCare cardholder."

Remember that you have to reach the $30 mark BEFORE COUPONS!  My "before coupon total" at CVS is generally around $50 or more, so this shouldn't be a problem. My big question will be whether your purchases will accumulate throughout the time period above. In other words, do I need to buy $30 THIS WEEK to get the promotion? Or can I spread out the purchases over a few weeks to reach my $30? I will update when I find out. :)
