My contractor over-ordered 8 bundles of Estate Gray 25+ year warranty shingles, from Lowes https://www.lowes.com/pd/Owens-Corning-25-Year-Supreme-Estate-Gray-AR-3-Tab-Shingles/3371130 . They are just outside of the Lowes return window. They go for $40.48 per bundle and I’ll sell them for $25 per bundle, $20/bundle if you buy all 8. All are new, still in the wrappers.
