in Blue Print for $39.75. Free shipping with Prime.
I have one of these and use it just for the beach. It works great even on the soft sand in Florida. I can put three folding chairs, a cooler with a bag of ice, 12-pack of drinks, water, and lunch in it, 7 ft. umbrella, towels, blankets, and all of my wife's stuff on it and it still pulls really easily. From reading the reviews, there are a lot of other uses for this cart other than the beach.
