Since the $5/1 Hungry Hungry Hippos coupon came out I've been looking everywhere for it! Target and Walmart are both sold out in my area and Walmart's won't come in for 2-3 weeks!
I was checking out the new ad scan for Walgreens 12/19 - 12/24 on iheartwags and it looks like the travel sized will be on sale for $4.99 starting the 19th. You'd have to snag them that day, since they expire early, but if you haven't found your games by then you have a shot.
I'm seeing them on the bottom of page 9, fyi.
