The trick is to not drink so much before bed time, hahaha...just kidding
What size do you need, a friend of mine built some deli display cases and last I knew he had quite a bit of extra left over and was looking to get rid of it, I donno what it would cost to ship but Im sure it would be ALOT less than buying from a dealer...I have no idea where you live I guess, so I cant say for sure.
I will ask him about it tomorrow when I see him.
