Cart Rules

[dhall111]

I'm stumped. I'm running 1.7.1.2.  I'm trying to create a discount/cart rule/voucher/coupon code - whatever you want to call it - that will give our customers a $1.99 discount on each and every item of a group of items.  We sell beef jerky (www.bubbascarolinajerky.com) and we want them to get that discount on any of our regular size bags.  But I can only get it to work on a single bag.  If they buy more than one bag it only takes off a total of $1.99.  Is there any way to do this?  It seems like it should be so simple!  I moved from livesite which isn't really a shopping cart system with very limited features - and they could do this!  So I am shocked that this seems to be so difficult. Anyone have any ideas?  Thanks,
