Leslie's Pools has all of their vacuum equipment marked 20% off their normal in store pricing until 7/31.

They have the Aqua Critter for $127.99 + tax, which is the lowest price I have seen since the beginning of the swimming season this year. The next lowest price is $139.99 at In the Swim.

They have other vacuum equipment on sale besides the Aqua Critter, but that is the only vacuum I have been keeping an eye out for so I don't know how good the other prices are at the moment.
