I figure we should start a thread about sales because I'm usually looking for them and why not! Post any sales you happen to see or know about here relating to bettas, equipment, maybe other compatible fish as well.
Anyways, at Petsmart 50% off bettas until 6/21/10! I'm assuming with the PetPerks card. They also have a whole bunch of fish for $1 - otos, some tetras and barbs, gouramis, and guppies.
