Looks like an older snap on box. I would prob go 150.00 on it. Seems like similar style snapon boxes sell for around 175-200 in my area. So I would try to pay under that. That chest looks like its in nice shape tho.
Check out the Harbor Freight chest and box. It is on sale for $299.99 this week. 16 drawers between both boxes.
As stated I would go about $150 for the box $200 if you really want it and that is where I would stop. I buy and sell estates and shops and I never pay over $100 for resale. When I buy an estate I seldom give much for the tools.
I think I'm gonna wait because he has been just keeps lowering the price I bet I can get it for cheaper if I wait. If it sells then someone just saved me from cluttering up my garage even further.
I'm pretty sure that is the current design so that box is probably not that old. I'd buy it if I had a use for it. That looks to be a deep box, a lot of tools can fit in a chest that size.
