There is a special sale this week on the Eriador quest pack Bundle. Until Thursday July 26, it is only 998 LP, 75% off the regular price of 3995 LP. It includes all 8 pre-Moria quest packs: Angmar, Enedwaith, Eregion, Evendim, Forochel, Misty Mountains, North Downs and Trollshaws. The regular price for one of those quest packs is 595 - 795 LP, and the usual sale is 20% off, so if you need even a couple of them, this is a good deal.
Note that VIPs do not need to purchase quest packs (in fact, they won't show in the store if your subscription is active), since the content is included as part of your subscription.
