When I bought my peitite ovals and petite scallops, I bought the set of four and saved money. Plus I signed up at www.cutathome.com
for a monthly 40% off coupon on one item and saved even more.
When I say "set of four," I mean the Petite ovals large, Petite Ovals small, Petite scalloped ovals large, and Petite scalloped ovals small. You know that when you buy the nestablities that the large and small of any shape are coordinated to stagger every other one for size, which means the smallest oval small fits with about an 1/8 inch border inside the smallest oval large, etc. Does that make sense?
I never planned on buying so many Nestabilites, but I love using them.
