Did you try asking at customer service desk? Back when I worked at one of those stores and dinosaurs roamed the earth, I would have put that through for anyone that came up to the cs desk and asked, as long as they didn’t do a mountain that draws attention. Around the time I left though they took away the ability to enter quantity multipliers without an override, and while technically cs reps have override auth they generally aren’t allowed to use it on themselves without permission (which would be granted if no other super or cs rep was available in a timely manner). Before that change it was possible (as a cs rep at a cs terminal) to do any number without override as long as the current price wasn’t also a limit price which would make it require two for some reason. They also got really annoying about the override logs around the same time.
Edit: I mean asking to have more than the limit at that price on the basis that you would have bought them multiple days, rather than a raincheck.
