I got a reply to the email I'd sent this weekend about their free samples. For a grand total of $35 for shipping and handling, they'll send me the following:
"Our sample cases come with a quart of Gaia, Medusa, Zeus, Demeter’s,
Athena’s and
Herculean Harvest. As well as an 8-ounce bottle of Khaos and
Olympus up. It will also include a feeding schedule."
Gotta scrape up a few more $$ to play with, but considering the rave reviews so many seem to have about their products, as well as how much any 1 of those quarts seem to cost on their own, it seems like a no-brainer.
