Thought I'd share this...
I found a great deal on a roto-molded cooler.
100 quart for $200! A 105 quart Yeti is $500 on Amazon, RTIC 110 quart is $499. I ordered and got it in 3 days for FREE.
It check all the boxes; rubber sealed lid, tight fitting rubber latches, lockable lid, hinge molded in, rope handles.
