I found a pet house on clearance for just $1.49 this morning at my Walgreens store! Hurry to the store to scope out this deal. I found a Pet Shoppe brand fabric dog house on an end-cap near the pet aisle. The clearance price was unmarked, but I had my cashier scan it and it rang up for $1.49. It seems to be included in the 90% off Christmas clearance sale. This is a small pet house, so it would work well for cats or small dogs.
Note: Clearance varies by store.
