Here are some facts about B&H and the Mac mini...
B&H is at this point a mass retailer that has just finished, or is soon to finish, a new 500,000 square foot warehouse.
B&H was not going to have, and did not have, any configuration of the Mac mini when Apple did.
Its ability to deliver was entirely dependent on Apple's own demand, notwithstanding the fact that B&H is an important retailer that has expended a lot of effort on being seen as an Apple reseller.
This is not different from other high end gear. If I want a Sound Devices audio recorder on day one of its release, I am going to get it through Gotham Sound, not B&H, which will have it anywhere from a week to a month later. You want the latest high-end Leica camera on release day? Don't order it from B&H. You wanted Freefly's terrific Movi Cinema Robot gimbal for iPhones when it was released, well I did, and I got it directly from Freefly, not B&H, which had it about six weeks later. By the way, Freefly has just announced that you can now purchase the MCR in Apple stores.
And why would you order a Mac mini from B&H rather than Apple on release day? There is only one plausible reason, which is that you are trying to engage in tax evasion. Either that, or you have some mishigas* idea that B&H will somehow deliver the computer that you want faster than Apple will.
B&H became potentially attractive to a small number of purchasers on 15 November, when it offered certain non-base configurations. I already gave you the link for that, see posts 23 and 25:

If you want to purchase products from B&H that are new to the market, realise that you are going to have to wait a bit and
use the tool that it offers you to be notified immediately when the product that you are interested in is in stock.
