I have for sale one box of 6” x 4’ (24 feet) plus 3 sections (12 feet) EasyOn Gutter Guards from Costco. I ended up buying too much.
See https://www.costco.com/p/-/easyon-gutter-guard/100019377?langId=-1 for a full description.
Costco sells a box of 24 feet for $64.99. I am selling the box plus an additional 3 sections (approximately 36 feet total) for $35.00. The box is unopened, and I have an extra bag of attaching screws.
