blown shock and need suggestion

i recently washed my car and noticed that my rear right tire was like very low then i checked the other side and it was perfectly all right cept the other side was like the wheel was tucked in and i think i just might have blown a shock , and i was woundering if driveing with a blown shock is ok or dangerous cause i dont really have time to get it fixed and if i do need it fix im thinking i might as well get all the shocks and springs changed, i currently have Tokico blues with h and r and i was woundering if there were any sites that offer like a package deal thats kinda cheap
