PetCo: Up to 40% off Fish Aquariums and Kits + Free Shipping

For a limited time, hop on over to PetCo.com where they are offering up to 40% off select fish aquariums and kits! Even sweeter, you can score free shipping when you use the code freeship at checkout.

As one idea you can score this Tetra 1.5 Gallon LED Desktop Aquarium Kit for just $20.99 shipped when you use the code freeship (regularly $29.99) . Seems like a great deal seeing as Amazon has this priced at around $26.
