They must have at least 3 copies for it to show up as "in stock." The Best Buys near me used to get three copies of the Criterion releases they stocked and they would show up as "in stock" on the online inventory. Around the time Late Spring came out, they started receiving only 2 copies and they would not show up as "in stock." I was at a Best Buy a few hours ago and it had 2 copies of Equinox (both of which have been there for a couple of weeks), but the online inventory does not show the item as "in stock."
