Walmart offers The First Years Take & Toss 10-oz. Sippy Cup 4-Pack in Rainbow, model no. Y1176, for $2.38. Opt for in-store pickup to avoid the $5.97 shipping charge. That's tied with our mention from last week and the lowest price we could find by $3. Each BPA-free and dishwasher-safe cup has a valve-free, spill-proof, interchangeable lid. One travel cap is also included.
Note: Amazon has it for the same price as an add-on item when you spend $25 or more.
