Right now Amazon has this Pyrex Storage 14-Piece Round Set, Clear with Blue Lids for only $15.00. I love this set! I have two of them and use the All The Time! The lids fit super tight and you can put leftovers in them warm without worrying about warping, then pull them out of the fridge or freezer and put them strait into the microwave. Nice. To make this deal even sweeter you get Free Shipping with Prime or $25 FSSS.
As with all Amazon deals, the price can change at any time.
