Spring breakage – Replace complete shock absorbers? Costs

Hello, just come from the lift – I have a spring break on the rear right. ATU has made the following offer – please give me your opinion: (Please don’t have opinions like – ATU is anyway crap or something, have made my own experiences) – 2x screw spring incl. installation on the rear 291,08€ The good man pointed out that at the moment the dampers are on offer: -59€ incl. installation/page would mean that I would be almost 400€ for completely new shock absorbers and springs on the rear Is the offer ok? The car is BJ 2001 and has now run about 170,000km. Is it worth it to catch up with other offers (possibly also from Volvo) or is the price real? Thanks and greeting Fabian
