Amazon probably lowered their prices because of Target.
Target ad I'm seeing has Season 4 at $59.99 and Redemption at $12.99.
BUT WAIT, THERE'S MORE!
As with Season 3 and Best of Both Worlds, buy both and get $10 off.
So... that's like getting Redemption for $3. Or both for just about $63. Not bad.
Now only if I can find them at a Target store that morning. If not, I'll just get Season 4 alone from Amazon, and hope it doesn't get f'd up in shipping.
