I het plenty when I harvest plants. But I've been frustrated because I need 5 more duct tape and cannot, for the life of me, find any! I rarely get them by harvesting and I also rarely get them at my Level 27 Newspaper. If I do manage to see them, they're sold out before I could even bat my eye. I have another farm which is Level 9 and the upgrade materials show up more but they also sell out so quickly :(.

I've been frustrated because I keep on selling stuff just to accomodate more things at my barn.

Do you have any tips? Like perhaps one that I read here wherein people said that people who are Level 151 often sell axes and saws.
