make me an offer BMW snow chains for low profile run flat tires

My dad had a BMW (think it was a 3 series? 4-door sedan) and sold it but he kept the snow chains which were never used. I'm not an expert in these, but the model is 36 11 2 305 414 which I think is for 18 inch tires. Everything brand new - carrying case, chains, etc. The price for these new seems to vary quite a bit based on where you're looking, so make me an offer. The local BMW dealer quoted I think $800 which seems a bit high TBH. Best way is to email me and we can arrange to talk after.
