Not sure if this is the best place for this, but I thought the most folks would see it here. Mods of course feel free to move.
Anyway... Petco has the 5 gallon Marineland hex aquarium kits on sale for $39.99 ($10 off reg. price), if you have their PALS card. That's the best price I've been able to find except for Amazon at the same price plus shipping. They also have Aquatic Gardens brand submersible heaters on clearance. I picked up a 50 watt that was marked down from $19 to $11, and rang up as $8 at the register! 8O
Seemed like too good of deals not to share.
PS - No guarantee you'll find either at your local store.
