I was in the Walmart in our town yesterday too and wanted to buy some of the plastic on a roll. I went and ask a clerk if I could get someone to help me and they said they paged someone. I stood there for 10-15 minutes waiting and finally left but as I am looking around I saw a lot of empty fabric shelves. I wonder if because of the pandemic that fabric is not being manufactured or if Walmart is slowly closing out their fabric area???
