I have multiple accounts and the arms supply has run out but it says it is good till October 8 on my..

I am not sure what you are asking here, if you want to renew the arms supply to have it run again on the main base then you will need to wait for it to expire and then purchase it again. If you don't want it then you will have to wait for it to finish on the 8th. If you set up a subscription (recurring monthly payment) then you may need to cancel this via your App store account.
