Question about membership

Hey guys I just wanna make it clear for myself. Lets say that my membership last for 10days more, so what would happen if I bought an upgrade at that moment? Would I be member for 40days or 30? Thanks

 

40, you never loose your previous membership days if you extend your membership

 

Thanks

 

Answer given.
Extra information:
There's a certain period of days at which you can't expand you membership.

I think it's something like 30 or so.
So if you have 30 days membership left, you cannot add another 30 day card.

Think it's like that.
