If you want to road trip down to Concord this weekend, the Equestrian Exchange is going on at the Cabarrus Event Arena. I went yesterday and there are a lot of bits. Pretty day for a drive, but a bit windy!
Google "NC Equestrian Exchange". Lynn Beason is really nice and puts on a great consignment sale. I've sold there for the past few years and cleaned house big time before we moved. There are always tons of bits.
What bits are you lookin for? I have many I don't use as I mainly ride Color is a hackamore these days. I could always mail something back to NC.
I highly recommend The Barn Door Consignment. It's a cute shop with very nice and knowledgeable owners and they have a wide selection of tack, horse clothing and stuff for people too. I've gotten tons of great items there.
