LOL, I rescue lots at full price too.
The walking iris is a good deal, I love mine, found it at a plant show for six, so you did good.
I always go to the clearance racks, it is hit or miss, but some of my best plants have come from them. Sometimes I buy an almost dead plant for the nice pot it is in.
This planter is full of .50 clearance plants. Got them all back in Dec and Jan.
