Another way to get some money in GTA 5 is robbing stores. GTA 5 robbing stores, not too profitable way of cash earning, on average, each store will bring you no more than 900-1000 dollars, however, if you have quite a trouble with money, it should help. This page added GTA 5 map stores to Rob, which you might find useful, as in a single game, these points are not marked on the map. GTA Online robbing store is no different, only thing is there's one more of them. An additional store is located on the first floor of the Trevor's meth lab.
Commiting a robbery of the store is quite simple. Come inside and reach for a gun. Under your sight, the seller will immediately begin to frantically collect money from the register. If he does not, or does, but in your opinion too slowly, you can blow up a couple of showcases with your shotgun, that'll help seller to hurry up. Sometimes, as sellers seeing you're holding the gun he will try to shoot off your head with a shotgun, then, alas, there is nothing to do, but kill him.
