Silly(ish) question...

Someone just bought 40 pie tins off of my trader.

Why??????

Stocking up a guild or do they think they're not reusable?

Oddly, someone recently bought 5 cake rounds, too (most likely would have bought more but I keep, at most, 5 on trader since they don't stack).

Someone else bought 20 muffin tins...

There are a half dozen quest recipes that do not return the pie tin, but I cannot think of any reason that one would need forty of the things. The Tinkered Gnomish Compass uses a pie tin, but I cannot see that being a big selling item, since it basically just duplicates the compass already there in the UI.

Did they want to corner the market for a higher price maybe?

Then they're mad because I made 40 more and put them on my trader.
