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 for $19.99. Of note: I think that full sets, while more expensive, are the most economical. All purchases count towards Amazon's $25 off $125 coupon code in Kitchen & Houseware. Shipping is free; there is no sales tax to most states.
