To get away when you are wanted go to nearest cloth shop and buy a new pair of cloths.
Big Money Tip
The best shops to rob is the gun shops. They will give you the most money $800 plus so go try it and let me know if it works.
Scrap any car at Bruskie's yard for 500 each (give or take) or find and steal a two door sports car and export it a Dereks for a couple grand.
When robbing any store you don't have to kill the owner, just go to the register and take the money. But, if he want to fight defend youself.
