Right before we got our Roo in late July, CW had the two pack on sale for $80 something, and I picked up a set (thinking that was a good deal) when I was in the store getting our sewer hoses and such that we were gonna need. Got to the register and the cashier picks up the x-chocks box, hands it back to me and says, "would you kindly put that back?" and gives me a wink. I reluctantly took it from her back to it's spot in the aisle, and when I returned, she had 2 singles from the endcap of the same aisle (that I somehow missed
) which was full of the singles on sale for $35~ish.
I was grateful for that cashier.
So far we have only used one, but noticed a big improvement in wiggle-jiggle with just one, so I think two will be great.
