Petco has Christmas clearance marked down to 75% off. Also, at the front of my store they had bins where the item inside was 1.00 or 2.00 dollars. I got a really cute 5 piece toy set for 2.00. It included a rope, 2 squeekers and 2 tennis balls! I got a pack of candy cane rawhides as well. Don't forget to use the 5 dollar off a 25 dollar purchase coupon. You could really stock up!
Petsmart is also marking down their Christmas clearance to 75%. Pet calendars are included in this deal, they are around 4 dollars.
