Have a look, I would. You decide. But there are potential savings. The seller says, "This is a $144.33 savings"...but it depends, surely, on the cost of these coupons. I suspect though that they will go relatively cheaply. I think you can buy them now for $2!! Go for it.
In which case you get big time savings which will be particularly attractive if you normally buy Blue pet food.
This is the ebay page. Coupons expire 7/30/11 - this is USA pet food please note.
