Hi EileenT,
Welcome to the Mattress Forum! 
I think you’re referring to one line in a paragraph describing the consumer membership in The Mattress Underground:
In addition to the resources available on this site, our mattress forum offers personal guidance about your situation and an “analysis” of any mattress you may be considering. We will help you find the best local manufacturers and retail outlets in your area and if you choose to purchase from one of our members, you will also receive the additional membership discount simply by letting them know you are a member of The Mattress Underground. With the help of the resources on this website and the personal guidance from our forum, you will quickly learn how to separate “stories” from fact. Most important of all, you will be able to find the manufacturers and retail outlets who will give you information you can trust to be accurate and helpful … outlets that care more about helping you buy a great mattress than they do about “making the sale” or putting profit and commission above your long term satisfaction.
The goal of this site isn’t to find retailers for you, but to provide you the resources in order for you to learn how to evaluate and select an appropriate and quality mattress, such as in the mattress shopping tutorial here, or advice about selecting a retailer in this article here.
A great place to start your shopping would be the members of this site. I think very highly of them and I believe that they compete well with the best in the industry in terms of their quality, value, service, knowledge, and transparency. They are extremely knowledgeable about mattresses, and I would not hesitate to recommend any of them for your consideration.
If you are thinking of shopping locally, you can provide your zip code and I can see if I am aware of any better possibilities in your area.
