Im guessing a run to Wal-Mart would be too much to ask??”
When ‘IT’ really hits, a trip to Walmart will be futile, as they will be cleaned out in hours, if not minutes. The key is to ALREADY have your inventory - at least for 4 years of normal use, or so.
If not, have fun waiting in line after line to try to grab what little crumbs become available (after we collapse...which WILL be soon).
I don't think crumbs will quite do the trick here.
