I would concentrate on promoting the site itself with a short descriptive blurb you can post many places. The only suggestion is break the products down into categories like, banking, meat, seafood, beverages, all the food categories for ease of access, insurance, internet providers, tech providers, etc. etc. etc. I have started this in my own small way the last few days, and will certainly promote your site, if you like. Could also help if you need some relevant tasks done.
