You can price match, but the products must be identical. They will not price match anything general like "so and so gallon aquarium." Seeing as PetSmart rarely carries All-Glass Aquariums, I wouldn't count on a price match happening.
has anyone tried with larger tanks? a coworker of mine went in tonight and got a 120g for $120. they had to order it and it will come in 5-10 days. im gonna go try to get a 75g tomorrow
