Saw this clearance deal at a local Tractor Supply Company (TSC) this evening (5/22/18). The 4-gallon Baby BiOrb was originally $69.99, but is currently clearanced at $13.99, an 80% discount. Much of the accessories were also on clearance, ranging in price from $2.19 - $21.99. The 8-gallon was only discounted $20, so not as good of a deal, but if you're in the market for a small (starter) tank, this would be a good one if you can find it at your local B&M for same price.
