Is Autopay worth to use

I have joined and Upgraded to Ultimate on 8th july and with1100 RR now , want to know the opinion about Autopay from you all as it is said , autopay works here when there is at least 20 days left for the next payment of RR , so I need to go for it if it is worth using it.
Also Is it confirmed that 20 day rule is active here? if so I have 4 more days to start it now , so please friends I want your advice about starting Autopay ,

Hi,
first of all, the 20 days rule is not here, autopay will work even if your rented referral have 1 day left, if he made a click, autopay will extend this RR for an additional day.

autopay save 10% discount on the RR price, its surly a great way to save, but the regular extending methods can reach upto 35% discounts which its much better and will increase your profits to the max if you can afford the requered budget

Thanks Sir , I have got my reply so fast from you
