Nuby 3 pk Insulated Cool Sippers or 3 pk Brushes for $4.81

 

I wasn't even looking for these while shopping at Sam's Club but I thought it was a really good buy considering Amazon sells these for $6.99 EACH.
After trying other cups, this one seems to work the best. It doesn't leak and doesn't have the spout/nipple. That's good for us since Maya loves to use the nipples like they were paint brushes on the couch (the milk being her 'paint').

You can order both the cup or the brush sets here for shipping or pickup at your local store (if available).
