"how likely are they to roll this out to all their stores should it prove beneficial? "
Crystal ball question but here's my best guess. Gary and Scott (CFO) will definitely do their due diligence. They know very well that mobile marketing is where they need to be. While they are an aggressive company on being on the cutting edge I can also promise you that much of this will fall on Dave to be communicating with these guys just as aggressively. They are a very cordial and respectful group they hold their vendor partners feet to the fire with prompt service and helping them to easily apply their services/products to best fit and help KT with what they are trying to do. So it's in Dave's best interest to study this company and ask lots of questions and help pin point an opportunity to promote products they are pushing or need help with. This done correctly will allow a footprint for the others like Love's, Cumberland, Circle K's etc. At the end of the day I can assure you Dave will have to be immersed and heavily involved to see and help make this a successful test with results they can realize. Expecting the store mgr to make this all happen will never make it a network rollout. So I say more of this depends on how Dave treats this opportunity. IMO...it's his to lose given their focus on "be where the customer is" mobile marketing.
