Good to deal with. Their parent company is Intrepid International, which is a large wholesale distributor. I ordered some Thinline insoles a few months back and had a smooth, quick transaction. I'm pretty sure they are shipping out of South Central PA, so shipping time will depend on your location.
They are NOT the "old" Horse Tack Company from a few years back, but I believe Intrepid bought them out about 18 months ago.
