Consider the sheer cost of this. Shipping, especially overnight shipping, is incredibly expensive. Stores get stock on on or two regular days of the week and have a crew dedicated to just unloading that truck and getting everything on shelves, a process that takes days.
Stores could not profit enough to put items in your path in the hope that you might buy them in this way.
I don’t think it’s a joke or even paranoid, just a bee noticing the effect of a quirk of human brains.
Noticing an illogical thing because their brain took a shortcut and dusted the fallout under a rug isn’t an easy experience. The first instinct is not to assume our mind has broken, it’s to try to find the answer to make the event explainable. Often that involves thinking only inside the scope of the event because no other information is immediately apparent.
