Rickochet The closest to me is El Paso, 45 miles, and not worth it. Letting my membership drop this May. Not sure if they get paid, but the El Paso COSTCO shares a large goofy shopping center parking lot plus every Dentist in Juárez offers to pick people up at COSTCO and bring them across the border for cheap, but quality, dental work. The place is busy but not so much inside the COSTCO.
