I was looking for a deal on my dog's prescription flea medication. I usually purchase it from Drs. Foster and Smith. They're having a 10% off prescription pet meds and I thought it was a pretty good deal since almost all their sales exclude prescription meds.
Being a cheapass, I searched for any additional online rebates back and not surprisingly they do not have it for Drs. Foster and Smith. However, I did find out that Petsmart is having a promotion going on in their pharmacy (I think their pharmacy is relatively new). Their deal right now (till 8/28 I believe) is 20% OFF your first RX medication order PLUS an extra 20% off first auto ship Rx order (this you can cancel any time after your initial order).
I normally order Bravecto flea and tick medication for my dog and it costs about $43.99 EACH on Drs. Foster and Smith. I don't even want to talk about how much my vet is charging for that same drug. With this deal going on on Petsmart.com, I was able to order the medication for about $26 EACH (before tax). I ordered 3 so that came to about $88 total after tax and it was free shipping. Now my dog is all set for her flea/tick prevention for the next 9 months (each pill lasts 3 months).
