Guild Wars 2

I mistakenly purchased a bank Tab Expansion without knowing I had already reached the limit or the expansions and this made me think that there really should be a warning like there is on the Basic Node Pack and I think the Collections Expander that has this warning in it saying “You have already purchased the maximum number of this item”. I don’t understand why the Bank Tab Expansion doesn’t include this warning as if it did I would have known I had the max and wouldn’t have been purchased the upgrade and waste my gems. Could this be implemented with any Gem Store item that has a limit on how many you may purchase or use?

Sounds like a good idea.

I believe if you try to upgrade from your bank itself, it will not allow you if you have maxed the number of tabs.

You should be able to get a refund of your gems though so do contact Support.
