To me the most outrageous deal is the half price bus ticket. You will get small discounts at many pharmacies, restaurants and cinemas. The INAPAM website lists discounts but it is not a complete list and is concentrated around Mexico City. I always ask and am often surprised at the places offering discounts.http://www.inapam.gob.mx/

I'm not a resident, so I don't think I qualify for one of those cards. But after determining the asking price of one thing or another, and if it seems to me that there might be some room for negotiation, I will often smile broadly and ask "And what would the price be with the old folks' discount?" Sometimes the vendor will smile back at me and say that the previously quoted price includes the discount, but often they are willing to knock off a few pesos.I've passed some time, on three or four occasions, at an RV campground about 12 miles out of Zacatecas. From there, I take the bus to town. I've had a few short conversations over the years with a fellow whose job it is to verify that bus tickets are being properly accounted for. He walks down the aisle of the bus with a hole punch. Anyway he advised me to inform the driver, on boarding the bus, "Half price to Zacatecas!" It only saves me six and a half pesos per trip, but every pesito helps when you are retired and on a fixed income.

I forgot to mention, many times city buses are half price, I often use Meridas city buses and with the card, the price goes from 6 to 3 pesos. I think in Mexico City, you do ride free but need to get a special card which I have never bothered to do. Also, several Mexican airlines give a discount with the card.I use ADOs Platino buses often and without the discount , I would not go for the luxury of Platino. For example, I just bought a Merida to Tuxtla ticket and it saved me over 550 pesos.
