I'm looking around for the cheapest place to buy cork in semi-bulk and have come to the conclusion that it's freaking expensive! I'm hoping to get both flats/tiles and rounds/tubes for a new enclosure. Would an expo be the cheapest place to get them or are there companies that do discounts on large orders? I'd like to get about 50 sqft of tiles and several tubes that are at least 3-4' long and at most 6" in diameter. The best price I've been able to find online is about $450 before shipping, there's no way I can afford close to that.

If nothing else I'll just buy a couple pieces at a time and eventually cover all the walls haha. I'm also guessing that nobody makes branched cork tubes as I haven't seen any but if I'm wrong on that please let me know.
