This was the second of two calls in as many minutes from Thriftopolis.  They have called me on several numbers.  No option to take yourself off the spam list.   This time it was Bill with the Dav.   I will get more calls in the next few days from other charities telling me their truck will be in my area next week.  It's all the same truck going to the same thrift shop on E Colfax in Aurora.  It's the same thing every month.  I would not give them the lint from the dryer.  I suspect a scam.
