Lol they are garage sales on steroids! I haven't been in years but I used to love them and have gotten some great buys as well as plenty of stuff that I totally didn't need. I have more than a few beautiful stain glass hanging lamps that are not even installed and more antique medicine cabinets than any home needs, lol.
In general I'm pretty sensible and frugal but for some reason at a good auction my bidding hand just flies up on its own accord...probably due to the fact I have MS. Yeah thats it my spasticity caused me to bid on it.
