ARE STRUTS THE ONLY SUSPENSION? THERE ARE NO SHOCK ABSORBERS, ON FRONT OR BACK?

I HAD THEM CHANGED TWICE ON THE BACK SO FAR, NOW I WAS TOLD THAT THE FRONT ONES HAVE TO BE REPLACED, WHICH THEY ARE NOT CHEAP, HOW DO I NO I AM NOT BEING RIPPED OFF?

how often did you have the rear changed and why?who told you the front ones need replaced,and why?are you taking to same place each time?do you know people at shop,very well?also what brand struts did they put on rear?

FIRST TIME I HAD THEM REPLACED I HAD HIT A DEEP POT HOLE AT NIGHT, DIDN'T SEE IT COULD FEEL THE DAMAGE,LEARNED WHAT STRUTS WERE, COST $500 TOTAL,I NO I GOT RIPPED OFF. SECOND TIME HIT A POT HOLE AGAIN, DIFFERENT MECHANIC, $300. SAME MECHANIC WHO JUST FIXED MY BRAKE LINE, SAID HE COULD FEEL A DIFFERENCE WHEN HE DROVE MY CAR. I DON'T KNOW IF YOU CAN SEE POTENTIAL DAMAGE. I DONT KNOW BRAND.
