It would be great to have a multibuy promotion that allowed multiple products of varying price points to be included in the same deal.
For example a 2 for $20 that regardless of the individual item price would trigger the markdown to $20 as soon as a multiple of 2 eligible products were added.
That way if someone order 6 items the total would be $60 but if they only ordered 5 it would be $40 + a single item price.
Currently there is only a way to do such an offer on 2 products or every number over 2 and not just the multiples of 2.
