The company that sells this advertising, Adcart / ShopperLocal, has a long and illustrious past of complaints over their Adcart program and Register Tape Network product. If this is not enough let me share my personal story.
I sold advertising for this company to local businesses with both product lines. Now when I visit local businesses and shop in the local Winn Dixie and bump into people I sold advertising to I am accosted due to lack of return on investment from these businesses. I suggest you call the businesses on the sample ads they show you before making a decision on whether to invest in this type of advertising.
ShopperLocal and Eli Global is suing me for pointing out to local businesses the pitfalls of their products and unethical behavior of their General Counsel. I would warn anyone considering advertising with ShopperLocal’s Adcart product to reconsider especially if you will complain about billing issues or lack of ROI, you may be sued as well.
