Expiring points question

Do points I expressly purchase, not that I earn or that come with membership fees, also expire? I’d like to buy a bunch now and have them available for the next few months, but not if they have a 90-day expiration date…

As far as I know, all points expire, regardless of how you got them.

Okay. That means I should only buy them when I’m about to use them.

I think infinite stockpiling should be allowed. But no biggie.

Ich empfehle Dir, die Punkte erst zu kaufen, wenn Du sicher weisst,dass Dein Tutor wirklich Zeit hat.Die Punkte verfallen nach 90 Tagen.Kaufe nur so viel ,wie Du sicher brauchen kannst.
