I don't know what "dumpster diving" is. [Though it seems self-explanatory. Dumpsters are for garbage aaaand...He's lost on why someone would want to dive into garbage. Or why a perfectly good sewing machine would be found there.]

I've been to a thrift store, though. I don't remember seeing a sewing machine there, but I also wasn't looking for one.

[The thrift store trip had been for clothes and essentials. And Camila already had the machine in her basement. He does remember that the store sold mostly used items for a discount.]

I guess it wouldn't hurt to check.
