RockAuto Question

When I ordered hoses for my brakes, Rock automatically sells you two per order although it's not very clear on their site. I need to order new bearings for the rotors I pulled off of a 75 Dart. Rock lists the inner and outer bearings of which I need one of each per rotor. My question, when I put an inner bearing in my basket and the quantity ordered says 1, are they sending one inner for each rotor or just one for the left rotor.
Thanks, last time I called Rock I was on hold for 20 minutes.
