I was at T.J. Maxx the other day and came across a decent selection of products for pets at heavily discounted prices (as compared to retail). You name it they had it - treats, toys, grooming supplies, bowls, beds, etc. I picked up a Nylabone Dog Chew (the one shaped like a bone) that retails for $6.49 for $1.99. Got the Rhino Chew above for $2.99.
They also had an assortment of "high end" treats. I got a bag of Get Naked dental chews which retail at Petco for $7.99 for $4.99. The biscuits also retail for $7.99 at Petco but were marked $2.99 at T.J. Maxx. I picked up random products and checked expiration dates and they were all good. Marshalls (owned by the same company) also has a similar selection.
