Ecommerce vs Real Estate – Plugin Recommended

HI,
The company I work for is a promotional marketing firm. They offer discounted gift cards for specific businesses in the area, ex $500 restaurant certificate for $50 bucks. My question is, since we are not allowed to sell the certificate over the internet simply promote it, would it be wiser to use a real estate plugin or an ecommerce plugin? My thoughts are that with a real estate plugin I show a map of the location, pictures, videos, etc. If I use an ecommerce plugin, I know they are built to sell a product. What is your opinion and which plugin would you recommend using? Our current website is Atlanta Appreciation Events .

Thanks and happy designing!
