Nice offer Joe. I think there are more than a few stock foam chunks floating around looking for a good home.
Listing the year was a nice touch since covers have color accents that vary by year. For example I have grey in a 2003 cover and blue on a surplus 2006. Someone might really want your 2012 cover to repair or change theme.
Maybe we should all get together and donate our foam into a big foam pit and practice TW backflips. Double backflip into foam pit - YouTube
