Perhaps Red Bull takes into account some discrete pricing jumps that people might have. For example, suppose a single can of Red Bull costs $1.50 (you haven't given that price, but I think it's important) and I go in and see that 4 cans cost $5. So I see that it's a good deal and it's just a five dollar bill.
But when I get to 24 packs I'm in a whole different league and not thinking of an individual note. Now we're talking serious money.
typical single pricing for a can is $2. also, typical pricing for a 4 pack is $6-8. walmart is specifically pricing them lower than "market", if what the OP is saying is true.

Or perhaps Red Bull buyers can't do arithmetic.
