Citroen C5 I Break — Where can I get new shock absorbers

Hello guys, I was on Thursday with my C5 to HU and there the front shock absorbers were contested. So far, so good! Has already its correctness, swing after. Just… looking for suitable spare parts I have previously dug several online parts dealers and no one offers shock absorbers for this model!? Since my wallet is rather located at the narrow gauge border I of course look for the Cheapest offer! Can please help me DRINGEND and help me Where do I get the cheapest new dampers? Thank you for your support!
