Please excuse the newb.

I'm currently on 1.50.

How would I go about setting up price breaks like this:
1-4 of a specific item are @ the regular price
buy 5 get 6th free

It isn't a straight quantity discount where there is a price break past 5 items since if you were to buy 7 items you'd still only get one item free, the other 6 would be at the regular price. But if someone is to buy 10 they would get 2 free.

I hope that makes sense.
