Stop in for a cup of coffee

Picked up paint for them the other day at Sherman Williams, could only get a gallon really just need a qt, guy cut me a killer deal and he gave me so he gave me qt cans to store the rest in, The guy I get dist parts from wants 2 qts of it from me so It will be free basically, It will be a trade for door stickers. Yes I am a ***!
