Keeping Track of Discounts/Bonuses/Deals

Hi everyone,

Just curious to find out how everyone keeps track of all their discounts and bonuses or deals that come from loyalty cards, credit cards and company cards etc.

For example if I already have say a RACQ card, I can get discounts for many different theme park tickets, discount movie tickets, plus other activities etc. But you might also have a credit card that offers discounts or rewards bonuses for maybe some of these same attractions.

So my question is how do you keep track of all these discounts and bonuses for all your currently owned cards and loyalty programs?

Keen to hear how everyone does it.
