Recommendations for potting medium online store? (Phal mix)

[Corry]

Soooo, I was getting a bark mix at Home Depot before, but they don't carry it anymore, apparently, and I can't find anything other than that terrible Miracle Gro Orchid Mix locally. Soooo, I'm looking online.

Can anyone recommend an online store (or product on Amazon) that is reasonable with reasonable shipping? I'm from the U.S. and I'll be repotting two mini phals and four regular sized phals.

TIA!

EDIT: I'm very overtired. My apologies for my gratuitous use of 'sooooo'. :P

EDIT AGAIN: I forgot to ask: Is coco husk an ok potting medium for orchids? I was looking for coir today and found the much chunkier coco husk at Pet Smart, instead. So I do have local access to that.
