I have had a pie tin I made a long time ago, and I use it in baking alot, I recently noticed that my pie tin now stacks. Must have been added in a recent patch.

They are not just smithed, but also pottered. They are needed for many, many different baking recipes. Only profitable, I would say, if you plan to use them in other trade skills, (such as baking or tinkering).
You can also make a pie tin using the pottery skill. I don't know if they are different.

Total cost roughly 1p2g5s8c to make, 5g7s6c to sell to merchant, 7g5s6c to buy from merchant. Hard to see how this is profitable, but it has to be sheaper than the smithing route.

They would be available in stores only if someone sold them to a vendor but most likely you wont find one for sale anywhere but they are quite easy to make.
