They do have good prices! The shipping is almost as much as the tarp. I pretended to buy a 20' by 40'. The tarp was $85 or 90. The shipping was $65. I made a 16 oz tarp for my coal. It's 5 years old now & looks close to new. I'm hoping for 15 years. White lasts longer than black. They say the tarps are only weeks old....which may or may not be true, but I'll bet they tarps are less than 5 yrs old no matter what so you'd still get a fair deal. I say 5 yrs as the ink will fade in 3 to 5 years. Of course the ad may run less & you might get one that's only one season old. New 16 oz. fabric for a 20 by 40 foot tarp would be over $500.
