If I recall, your distributor had almost all of those already spoken for as well (and you had to convince them that you had them reserved before they would give them to you or you would be out of luck to get them). This indicates that even in your local area, the PHB is doing well.
Not quite. You're conflating two different anecdotes of mine. The above is my estimation of how many they (my distributor) had
initially - I saw the flats in late August, before they were allowed to release them (for the Game Store release date of September 3rd).
The time that I had to convince them was three weeks later, when I had started to run out, and had asked for MORE copies to be put aside. They initially told me that they couldn't fill that order, but I managed to (truthfully) convince them that our order had been placed while they'd still had stock, and they'd just 'forgotten' to set them aside.
At that point, they had a few
boxes of books (of 10 copies) - maybe around 100 copies or less. And those, were either spoken for, or they had wanted to hang onto them for whatever reason, because they initially told me that the simply didn't have ANY, but after I proved that there should have been some aside for me, they opened a fresh box and gave me seven of the ten. (I'd have liked more, but it was clear that it wasn't going to happen).
Here's another issue with the idea that "WotC only sold 3700 copies of the PHB" - that would mean that my own tiny little game store in a Canadian suburb would be "worth"
nearly 2% of their
entire sales (not that we report to bookscan). While perhaps chest-puffing, it's patently absurd.
