Amazon has the Rubbermaid 42-Pc Easy Find Lids Set for just $15.98! This is pretty close to the LOWEST PRICE it has EVER been $15...a year ago :)
This BPA-free set has lids that snap to the containers bottom and to each other so you can find the lids easily and nest them together to take up very little space.
This set has a near perfect 4.5 star rating from over 7,900 consumer reviews! I have this set and have no complaints...except that people borrow them from me and don't return them lol
