Shipping charges are important expecially with large bulky items like media orders. I like to find a vendor close to me. Go to "Orchid Mall"
The Orchid Mall - Everything in Orchids and look for a vendor close to you. Have a close look at the product then consider the shipping charges. CHC is a great potting media & I really like it for Cymbidiums and Slippers. Have used it for about everything but it may not be the best for some of the rest. Have had luck with most of First Rays
products but would have a look at shipping charges too.
