PetSmart Tetra Whiper In Tank Aquarium Filters on a big sale. These prices are online, not in store, but the rep in the store today told me that their policy is to match their online prices if requested by the customer. Just set it up in my tank and it works great, and it comes with everything to plug-and-play. Find the prices and tank size listed below, the sale should last until next weekend.

20 Gallon – $10.49 (reg. $24.99)
40 Gallon – $13.29 (reg. $29.99)
