Sealed jugs of green antifreeze concentrated. The current price of antifreeze is right at about $15-20+ per gallon with tax, everywhere.

$40 4gal CASH FIRM($60-80 value) $70 for 8 gallons Cash FIRM($120-160) I don't take Venmo or any other gibberish fake money

I don't really care if it sells or as antifreeze never goes bad in the jug. It just gets contaminated with rust/oil from the engine.
