HelpAge Introduced HelpAge Advantage Card some ten months ago. By simply filling up an application form anyone who is 55+ can get a card. Possession of this card has very many advantages. Most importantly you can get good discounts on a variety of products and services. Besides this, it can be used as an ID card (not for govt purposes though). Members can interact among themselves and read a blog. There are 1 Lakh members now. Some 600 establishments (shops / service providers) have tied up with HelpAge as associates.
Their website http://www.helpageadvantage.org/ gives a lot of information. You can easily find where, in which city you can find discounts. Database is easily searchable by city, category and subcategory. I could locate a good number of shops in Hyderabad.
Some of the adavantages mentioned are yet to be put in place. Use them and see.
