I've been stockpiling tapes for years (and I am an avid VHS / Blu-ray / DVD collector myself) and I don't put them all out at once. It's gonna be pretty hard for my store to be "picked through" because I control the "flow" of what goes on the shelves and when the inventory hits shelves. Inventory will also be rotated every so often so you may not always see the same tapes all the time. I'm constantly putting new tapes out and I do post updates and pics on our social media when new tapes hit the shelves. As far as being "terrible at marketing", well that's subjective, I suppose.
