ha, I dont think I can top fermis with that one....but after very first vendors experience I needed a wheelbarrow to carry all of my kits! LOL!
This one fellow had been left with a large stash of aircraft kits thanks to his father and brother. He had no need for them and was just handing them out pretty much like candy! All 1/72 scale kits were only a buck, and the larger kits ran form $5 for a ww2 fighter, with the larger stuff never passing $10!!!! IF you grabbed 3 large kits, he'd only charge you $15!!
That day I ended up getting 20 kits (14 in 1/72, 5 in 1/48, and one 1/32) and an aftermarket detail set, all for less than $50.
