Print a rare $2.00 coupon valid on any NUK product and head to Walmart where NUK Nautical Advanced Sippy Cups are as low as $2.31. Use the coupon and pay just $0.31! To get the coupon, register and play a spin game.
Inventory and prices may vary at each Walmart location. I recommend printing the coupon and bringing it to the store. There are a lot of NUK products to choose from in the baby section.
