Pet parents rejoice! The 4-page PetSmart Black Friday 2013 is packed with gifts for pets and pet-lovers alike. PetSmart will open its doors at 7am on Black Friday and give away a free treats-and-coupons-stuffed stocking to each of the first 100 people in line. PetSmart will offer over 3,200 items on sale at 50% off or more. Select tropical fish will be 5 for $4, saving you up to $4.19 each. If you're looking to bring something a bit cuddlier home, guinea pigs and dwarf hamsters are 50% off – reptiles too! All holiday dog apparel and collars are half off, with collars starting at just $1.64. Also worth noting is the half-off FURminator Deshedding Tool, priced at $18.99.
