Amazon is by far the best store to buy Calphalon, on account of both their pricing and their massive collection. One of the most affordable is this Calphalon Professional Nonstick II 8" Omelette Pan (pictured), now only $16.99. Of note: I think that full sets, while more expensive, are the most economical, in large part because if you spend $125 you can use Amazon's $25 off coupon code valid in Kitchen & Houseware. Shipping is free; there is no sales tax to most states.
