Found this as a part of Target's clearance sale, looks to be a historical low.
There's also a bunch of others on sale as well:

If your spending over $20, you get free C&C or free delivery over $45 spend. Don't forget to use cashback + gift cards to bring the price down a little bit more.
The retaliator looks good but it's ergonomics are terrible. It is not pump action like the box art depicts. You pull back the top part of the main body.
