I bought a bunch of stuff some years ago and I recently came back to Lotro, so now I forogot which quest packs I have, is there a way to see the whole purchase history?
I believe you can see that information when you log into Turbine: My Account.
This display is a VIP benefit.
Free and Premium customers can't see their history. These customers have to log into the game. Open the Lotro store. See which Quest Packs are available to buy. The ones that are not on sale - are the ones that your account owns.
All customers get Breeland, Ered Luid, Lone Lands and The Shire.
Unless stated otherwise, all content in this post is My Personal Opinion.
