Coroplast Alternatives Awesome cage liner find and idea

I went to menards today hoping to get vinyl flooring since i cant find coroplast. They had one kind on sale for 39 cents per sq ft. Well, it was gone. So putting my McGiever thinking cap on, roaming around, I came across floor runners. The type for carpet cuz of the bumpies on the bottom. They are 27" x 12', somewhere around that size for $ 4.79 ea. One of those would totally fit my 2x7 c&c. So, go get yourselves some while on sale. They are like half the normal price!
