The First Years has a coupon for $3 off a 2 pack of sippy cups.
These sell at Walmart for $7.76, So It ends up being less than $5 for two sippy cups!! This coupon is only good at Walmart, and only until April 6th.
All you need to do is go like The first years Facebook page, go to their "deals" link at the top of the page and find the deal. This is a great deal, you can never have enough sippy cups :)
