There's an awesome freebie event happening at that local 7-Eleven store! Today only, and then only while supplies last, participating 7-Eleven stores will be giving away free bottles of MiO liquid water enhancer. MiO gives new flavor to an old time hydrating beverage and is small enough to carry with you anywhere you go. Hurry, this offer is only valid while supplies last on 04/23/2013. No coupon is needed, simply ask for this freebie at the register.
