BJ's buy 5 Lifetime Full back chairs get 1 free.(in-club coupon)
Valid 10/29/15 - 11/25/15.
These are not exactly the same as those sold at costco. I don't remember seeing these chairs for less than 20 anywhere, so it's a good deal for anyone interested in 6 chairs.
There's also a coupon for the Lifetime 6' Fold-in-Half table $49.99 -$10.00 = $39.99
