I live near the first original Ollie's store, so I have been shopping there for over 40 years. The stores have been cleaned up over the years and now are easy to shop in. At one time, they looked like a hoarders basement. Nothing was organized.
I have gotten many bargains there. They have carried the RR merchandise for years. It is all first quality, unless it is marked as a second.
Most of the "seconds" are reconditioned appliances and linens, like sheets and towels.
I am sure you will enjoy shopping there. There are many bargains to be found.
