Looks like the waterless washes (in concentrate form) offered by Optimum and Ultima are cheaper* than a typical QD (Ultima's costs a mere 59 cents to make 22 oz. with the 16 oz. conc.) and they provide a very similar function....with the waterless wash providing better cleaning while still leaving some protection and gloss.
*Optimum's QD and waterless wash cost the same ($2.75 to make 22 oz. using the 32 oz. conc.)
Do you really need a QD?
