AquaClear HOB Power Filters 30g and 50g deal
Amazon has AquaClear HOB Power Filters for 30g and 50g that are at a good price: $25.99 at the time of posting: http://www.amazon.com/gp/product/B000260FUW/
As with all Amazon deals, two-day free shipping with Prime. If you're a student with a .edu email address, you can get a free 6-month trial. Very useful for college!
Edit: There was a $5 off $25 promotion as well...but it seems it got removed by the mods because it had a referral code (did not know, I just copied and pasted). Google it and you will probably find it.
