Based on personal experience with my mom, a senior citizen is entitled to certain benefits - 20% discount on medicines and fare, 5% on food and groceries. At least that's how it is here in the Philippines. Availment would also sometimes differ depending on the establishment.
Here's a list of what's needed to be able to avail discounts:
MEDICINE
- Senior Citizen ID
- Medicine purchase slip
- Doctor's presription
- Authorization letter and ID (for cases where a representative does the purchase on behalf of the senior citizen)
Note: Maximum that can be purchased is up to 1 month's use.
GROCERIES
- Senior Citizen ID
- Purchase booklet (depending on the town where the senior citizen belongs to, he/she is given a booklet that covers both fresh (meat, fruits, veggies) and other categories (milk, canned goods, etc.) or just either, falling under "Basic Necessities and Prime Commodities")
Tip: Certain establishments no longer give discounts to promo packs. However, they still allow earning of points with their loyalty card. Or vice versa. Either way, just make sure you get to at least avail either, if not both.
