Columbia County Bread and Granola review for SC Sales Motivator

I've tried to track the response to this app - I have seen repeat customers who have historically only ordered x amount and now, with this app in play, they have upped their purchase to qualify for free shipping and that's exactly what I want to see. But I think this app could work better for us. Mainly, I'd like to offer more than the one incentive, I'd like to offer a tiered series of incentives... I.e., spend another ten dollars and get a free gift, spend another ten dollars and get ten percent off. If the developers could expand the range and flexibility of this app, I would give this five stars.
