Vacuum sealer.
They are always available used at thrift stores and they are simple machines but I can reseal bags of chips or other grocery items.
You can make your own bags for cheap from a roll and then individually wrap portions for the freezer that stay longer and don’t get freezer burn.
And if you get one that has a hose attachment you can seal bottles of wine, mead, or Tupperware for the fridge if you get the right lids.
Oh 2003? Nah $20 stretched hard back then, especially if it was a thrift store. Man even as a kid I could get so much stuff with $5 at a thrift store, I think I literally got a PC and a DVD player for like $10. Nobody was trying to maximize profit on every thing cause more was on the way.
Hasbrown at McDonald’s were .80¢, they are now $2.70. That $20 was more like $67.50 in actual purchase power.
