From the NRA:
The NRA is currently offering half off Life Memberships ($500) for a limited time. This is a promotion we are doing on our facebook page as a thank you to all of our fans who helped us reach 1,550,000 likes! This promotion began today at 6:30 a.m. and is available for 48 hours ONLY. You can find the promotion on our facebook page at: www.facebook.com/nationalrifleassociationIf you've been thinking of upgrading your membership, this is a good time to do it.
As an aside, the NRA has more people merely liking this offer than any of the gun prohibitionist groups have followers on Facebook. Hmmm.
