I don't have a shopping cart feature (may do that for the dry goods only this year). So you have to go to your paypal account to pay for it. Or send a check or money order. Sorry. But I will get it right out to you once I receive the order and payment.
There is a lot of good info about it on my site, much taken from the Nutri Bac site itself. I use the product myself in new babies, new acquisitions, snakes that may be stressed for any reason, and any reptile showing any kind of digestive problem.
It doesn't ALWAYS work (depends on what is causing the problem). But it often works, and can't hurt, since it is not a medicine. It only puts back the friendly microbes that SHOULD be in their gut anyway, but maybe are absent or in low numbers for some reason.
