Unless you need a special drip pan for a certain type of grill, you need to go to Sam's or Cosco. Pack of about 30 of the 9 X 13 was only about 7 or 8 bucks when I bought mine a few week ago. They work great on my Weber Kettle and my Genesis Silver B. On my Genesis I sit it directly on the flavorizor bars under the grate when just using burners 1 and 3 for indirect cooking.
