If you have a local Micro Center (full list of 16 states at bottom of coupon page), then request a coupon good for a free pair of headphones! This promo is only valid through July 18.
These won't be the nicest pair of headphones ever, but they're perfect for the kids or to keep in the car for traveling. Plus free is free, I'll take it!
While you're at Micro Center, you might as well get these other two freebies they still offer: a free microSD and USB drive.
