Quantity discount by category?

[Hammerhead]

I'm trying to figure out how to apply quantity discounts on a category level as well as an item level.  For example, I have a line of stickers representing about 50 different styles.  I need to offer discounts such as 6 stickers for $5, 25 stickers for $15, and so on.  However, some stickers are more expensive than others.  For example I have $1 stickers from one supplier, and $5 stickers from a second supplier, so I need to also filter by vendor, so that the quantity applies at different rates to different suppliers.  Anyone know how to apply such a schema?

Thanks in advance!
