Hi Claudia, If you've got any dollar stores near you, you can find them there in single or multi-packs for only a dollar.
Don't go to Wal-Mart or any other place like that as those will often be more expensive for something you may end up throwing out after every spill. The dollar store is the way to go. By the way, they look like over grown cookie sheets, with raised sides, and they just fit on the bottom of the oven, in between the burners or heating elements, so it doesn't interfere with the heat of the element.
