Heritage is a company that was acquired by SRS a few years back. There is a pool supply side and a landscaping/irrigation side. I called on the Branch Manager and sold 55 gallons of 3126 on the spot at two Davis Pool Supply locations, as well as an Irrigation Station location. They use store number, date, initials or arbitrary POs. Be sure to check their website, because they fall under a lot of other store names. I sold to two Tulsa branches of Davis Pool Supply, and my buyers' names are JR Frye and Miles McCarver. At Irrigation Station, he also bought 55/3126, is located in OKC and his name is Jacob Rodas.
