Okay guys, here's the deal:
Overnight shipping will be required, but I did call them to get an estimate. I'm told their rate should run in the $25-30 range. Seeing as how they would be multiple people ordering, I can't imagine that the cost would be very expensive per person. What I'd do is weigh it out, since I'm getting heavier liquid cultures, and distribute the cost that way. I wouldn't think it would be more than a few dollars for the shipping once it's all figured.
Please let me know, as I'd like to place the order this afternoon, shooting for Wednesday delivery.
