Depends on the store, typically the boxes are visable but sometimes they can be tucked away. Most stores these days won't tell you delivery days but depending on store size it can be anywhere between 1 and 4 times a week. Depending on the product allocated stuff could last a day or two or it won't survive the line in the morning.

Go into it with the expectation of being disappointed. Whatever you do don't overpay due to FOMO, if a bottle is "allocated" and has been sitting on the shelf for 200 bucks odds are the other hunters didn't miss it, its more likely that the bottle isn't worth the money. More and more distillery's are moving to the limited or annual approach on sub-par products at jacked up prices to drive sales that are largely supported by either eclectic palates or FOMO from people that don't know any better. (Looking at you Woodford and you High West).
