Guild Wars 2

Hey,

I have had weird problems with trading post gem store. It was functioning properly before, but now two of my attempts to buy Karma Booster has failed; I never received a mail containing it. Because high price of currency exchange I have now lost nearly 2 gold coins for nothing at all.
Any help?

Is your mail box full?

If you have the maximum number of mail in your mail box you will not get new mail until some of the other mail is deleted.

I deleted some mail before, turned out it wasn’t enough so thanks for reminding me, got them now. But why does the mailbox even have to get full? Is there a purpose for it? like wtf
