If you’re an exercise addict like me, you’ll get this. Even if you’re not an exercise freak, you’ll get a kick out of triple stacking mobile coupons and in-store savings to score $100 worth of work-out gear (including a sweet pair of Nike Frees) for just 50 bucks with your smart phone. Oh yeah, and you’ll love earning an additional 5% back.

Here’s the great thing about being a mobile coupon extraordinaire: you don’t have to plan any of this out. Yesterday, I had a slight running shoe emergency and needed to make a mad dash to my local Sports Authority. I arrived with a tired boyfriend and just 1/2 hour to shop. I needed: a pair of awesome neon Nikes, running shorts, and a heap of running socks. I did not need: to pay anywhere close to full price.

I immediately fell in love with a pair of shocking salmon Nike Flex Frees that were on sale for $74.99, down from $85.00:

The in-store sale price was a good place to start, but I knew I could do better, so I quickly SnipSnapped a Sports Authority coupon for $10 off a $50 purchase or $20 off a $100 purchase. (Get SnipSnap !) Off the clearance rack, I snagged a pair of shorts for $10, plus six pairs of bamboo Adidas running socks for $16 total (they’re normally $18 for 2-4 pairs.) I bought a Pepsi for the tired boyfriend.

Here was where things got tricky. If you know me, you know I’m conducting an ongoing shopkick experiment to see if it’s really possible to score huge rewards with your kicks. I could have traded a little over 6,000 kicks for a mobile $25 Sports Authority gift card right there and brought my savings to $50 (shopkick rewards are gift cards, so they stack with in-store coupons just like a plastic Sports Authority gift card would). After some deliberation, I decided to keep my kicks. Only because I’m close to trading them in for another, entirely free pair of Nike Frees.

My cashier was really, really excited about redeeming my SnipSnap coupon. He just typed in the promo code and I was good to go.
