“I have been buying my dogs Trifexis for a long time from Alivet. Unfortunately, its a very expensive drug and the prices seem to just keep rising. Allivet has one of the best prices on the internet and the times I have had to call customer service, they have been very helpful. My one complaint is that it seems like I get a $5.00 off coupon after I have made a purchase but before I need to reorder. At that point the coupon is worthless. I think they could coordinate the coupons so I could benefit from it”
