Turbine is looking for you to like them on Facebook and they’re willing to offer up a coupon code as incentive!
Currently LOTRO is at 249,856 “likes” on their Facebook page. If they get to 250,000 by noon eastern on Monday, they’ll post a coupon code good for 10% off in the LOTRO Store. For every 1000 likes past 250,000, they’ll add an additional 1% off to the coupon code up to 15%!
These coupon codes will stack with sales already going on in the store to help you get even more savings on the items you want to buy!
