I think Costco pulled their sheet cakes a while ago right? Are they back? What's the most economical option to get a crap ton of pies/cakes in a fairly easy-to-prep or no-prep fashion?

For real? No way! I used to work in an office and every year we had several of them at least, for Halloween party and Christmas party. Since I don't work there anymore never been over there!

As of July they have them.

They do exist but they are not premade any longer. You have to order them a day in advance. Not a huge deal but not as awesome for the spontaneous cake smashing urge

Cool, thanks. How long do these sheet cakes last? Can they be stored at room temperature for a few days?
