Sears offers the Pyrex 8-Piece Mixing Bowl Set with Colored Lids for $17.79. (Target and Amazon offer it for about the same price.) Opt for in-store pickup to avoid the $8.25 shipping charge. That's the lowest price we could find by about a buck, although we saw a similar set for $3 less in March. It includes 1-, 1.5-, 2.5-, and 4-quart bowls with BPA-free lids.
