Does anyone know of any coupons for KMS Hayloft? I'd like to get some pellets from them but the shipping is too expensive ($16 dollars which is more expensive than the pellets themselves). I don't want to use Oxbow anymore because of the calcium (at least one of my piggies is sensitive to that, I can't feed romaine lettuce or their urine is white). If not can I order KMS from anywhere else or is there another pellet food with a better source of calcium?
