I buy a lot of food goods that come in glass jars, picante sauce, spaghetti sauce, even little jars from pesto, and pickle jars. I didn't have to buy a single one last year and I have even more saved this year. Just a tip for those who hate throwing money around you got to clean them with a touch of warm bleach water and leave them to air dry for a few days before using.
Amazon bruuh, got dem $11 press-seal air-tight jars. They hold like.... 5+ ounces. Fun colors to choose from; like red, or nug-green, so everybody in sight knows you're carrying haha.
