Issues applying multiple stacked rules

Hi Guys,

I am trying to get a buy 3 get 1 free setup with your plugin (your plugin has the best front end i have found). The issue is that i cannot get this implemented at the moment.

To achieve what i want, i am adding a bunch of rules that say:
– buy 3-5 get 1 free gift
– buy 6-8 get 2 free gifts
– buy 9-11 get 3 free gifts
etc.

This way, every 3 items, you get a free gift.

I cannot get anything but the first rule to apply. When i add 3,4 or 5 it’s all good and offers me 1 free gift. When i increase the items in the cart to 6,7,8,etc. i can’t get the second or third rules to apply.

Any ideas on this one?

Thanks,
Chris
