This deal has ended.
Amazon has a set of 4 Pyrex 6oz. Dessert Dishes for only $4.99, despite the set selling for as much as $30 elsewhere (this set of 6 is $38 at AceHardware.com). These, along with most other Pyrex ("the original glass bakeware") products, are well-reviewed (4.5 of 5). Shipping is free if you spend $25 (otherwise around $6) and there is no tax (except KS, ND, WA).
