Nice score! Yep, always ask. The first time I went into what became my favorite shop, I walked around and didn't find any razors. I found lots of blades, but no razors. On a whim, I asked the lady and she said, "There's a whole box of them." She took me back, and tucked away on a lower shelf was a cigar box full of safety razors. I'd completely missed it. Nothing fancy, but a decent selection at a good price. Over the course of a few months I pretty much cleaned her out. But I would've missed them entirely if I hadn't asked.
You've always been handy with a bow saw, which is good news, as you've never been handy with a bear trap.
