They're idiots! *s* I've done that before....go through the whole list of e/s and along with the ones you aren't sure they have, also check the box for one that you know is still available, then you add to the cart & it will only put in the ones they have. When I tried it but only tried adding ones I thought had been waaay gone, it bounced me back to the main MAC spash screen. It's insane and misleading and highly annoying....I wonder if they've gotten complaints & if so, why they don't update it.
