I just took a casual glance at it and picked the whole thing up and took it to the counter. It didn't have a price on it so I had to wait while the young girl behind the counter who "didn't know about tools" got her manager. I thought, "Great, the manger will know just enough about tools to think this is worth $100". The manger shows up and says, "Um, I'd like to get $15 for the whole bin."
And so you shall, dear madam, so you shall.
(Actually, it's an independent church thrift shop and they do good work so I rounded up to $20.)
