I keep going to buy adventure pack that are on sale, like the current Haunted Halls of Evenningstar sale, only to find that I can't take advantage of said sales while a VIP. I'd like to buy them for when my subscription ends, and can see them with the "character-based filter" turned off, but it seems a VIP buying permanent access to a questline is not an option.
Am I missing some method or button that allows me to buy them? Or am I just going to have to give up on sales while I'm a VIP?
Edit: Argh, changed the title before posting thread, and forgot to delete a word. "While they are still have" just sounds wrong.
