I can only think like most of their products at seasons end they try to empty the inventory. I've used this product for years and am extremely happy with the results.
The only over-lapping that I do is on the edges keeping from finding an uncovered area. When I lay this material down it is on ground that i have 'plowed-up' and raked free of potential weed seedlings.....NOT active growing weeds.
This material is as thin as a sheet of paper. Maybe they had a misprint where is should read 1.6mm Definitely NOT a 1/2" thick !!
