I sold to DaJaKoe I think, evapony and others I swear though I see you selling to them there will be no you selling nothing (just kidding just in case XD (get it jk lol I'm stupid)
Your prices are up to you, but I would suggest perhaps lowering them a bit - as many 130s with those stats or lower are sold for 10-15k. Customers may be annoyed if they find out they paid a lot more than their usual value. However, in the end your prices are your choice.
