While I generally agree with this, BB is by no means smooth at price matching. In my experience more than half the BB reps still don't understand GCU. This is especially true if you say try to price match something on sale at BB with a lower GCU price than originally paid but has a base sale price higher than the orig. GCU price. Usually have 1-2 reps that tell me they can't price match because I already paid less. BB reps also seem terrible at math and usually don't give me the correct price match (though often this works in my favor).
True, I forgot the GCU price would have already been lower so in this case, no need for a PM. They've never combined GCU with a PM for me, or at least they're not supposed to.
