Discount signs are the pink and black signs with the word ‘Discount’ written on them. There are a total of 100 signs scattered throughout the map and for the most part are located on the sides of roads in clear view. Each sign you pass by in free roam will be added to your map as a pink dot. After smashing through a sign it will change to a black dot to let you know you have collected it. Chances are you will discover the majority of these as you progress through the game and work towards ‘Road Trip’.

TIP: When looking for signs on your map, be sure to change the filter to display only discount signs as often then can be hidden under other icons.
NOTE: Any sign you pass by while in a race or event, will not be added to your map so if you spot one, it is a good idea to make smashing through it a priority after the race in case you forget.
