I just found out that Tractor Supply Co. brings in a veternarian on Saturday mornings. With a full line of services at reduced prices. No appointment needed. I picked up a flyer with all the details. On that flyer was a web address and I went ther to check out the prices on Revolution, as they said it would be a reduced price. It is reduced quite a bit. $63 cheaper than my vet on a 12 month supply. That's a great savings!
