I keep coming across amazing deals at this petco so I just wanted to give people a heads up. For some reason the manager loves discounting ZooMed aquarium products. I picked up a ZooMed 501 for $12.00! For $23 I couldn't resist having one as a backup, but it rang up for $12 instead so even better. If you live around the area you should venture in from time to time. Look for dusty boxes and orange discount price tags on the product itself.
