Dollar General partnered with Mars Inc. for a seasonal bulk-purchase incentive offering shoppers $2 off the purchase of $6 worth of select confectionery brands from Aug. 21 to Sept. 24. A home page display ad on dollargeneral.com, a feature in the digital version of the retailer's Sept. 17 circular and an ad in a Sept. 22 email plugged the deal and linked to a promotional page.
