How to transport several pies?
I may not get a vote for this (hell, possibly a downvote), but....

Can't you just buy some bamboo steamer baskets from a chinese grocery and figure a way to stabilize them while they are stacked together? They are available in many sizes, and I am sure this little hack would work just fine.

Also, having checked google, there are very few inexpensive options.

PS I like your name, it's spelled the cool way, just like my wife.
