I am familiar with the Epic thrift stores in Las Vegas, but I've never shopped at their outlet stores.
The outlet store is where they send merchandise from their other locations.
The selection seems to be a mix of good stuff and some of it doesn't look worth more than the price tag, but you never know when the next item you look at is the one item that you just have to bring home?
My advice is to check back frequently, because at these prices you never know what you'll come across.
