Can't Wuxi sign online at a 15% discount below the filing price?

This depends on the specific difference between the actual contract price and the filing price, and then we can determine whether the house can be signed online. Now there are relevant regulations that the online signing price cannot be lower than 90%~95% of the contract price, but if the price does not exceed this range, you can also sign online normally, and everyone must know the specific price before signing online, so as to better protect the legitimate rights and interests of individuals. Signing a contract online is really important, but you must read the contents of the contract clearly. If there is a problem with the contract, it needs to be raised in time.
