Product review (4 stars): Menards stocks this product!!
After buying some 4" vinyl tubing from west marine at two bucks a foot, I kept my eyes open over the next week to see if anywhere else stocked it for cheaper. Luckily I came across this product at Menards for a fraction of the price.
As others have mentioned it stinks. The stuff at west marine did not but it wasn't worth the extra $30 for a 20 foot for chunk! I returned it and went with this product.
