I'm tired of seeing "frag packs" at retailers

If they only have a few rare corals, they probably didn't lose any money as the pack probably sells and they make more based on selling all 5 corals then just the one to you. If they don't sell the pack and the corals starting backlogging in their inventory, they will eventually sell them as individual frags or lose money.

Personally I like packs when I am starting a new tank as I get a bunch of corals for cheap (Cheaper). I hate packs when I have most of the corals I like and just need a few last pieces that no one wants to sell individually.
