Attached below is an example. I called customer service but they were useless... How do I post a dropdown box with quantity choice of X, X+5, X+10, X+20 for different price perunit?

I do NOT want to use the buy 1, buy 2, buy 3, buy 4 or more discount because that doesnt work for the above splits...
