Lulu.com is having a one-day flash sale with 30% off books and calendars from their print-on-demand catalog. I used the opportunity to finally pick up a full set of the issues 1-50 of Vinyar Tengwar from The Elvish Linguistic Fellowship. There are a lot of important articles in this journal, including many primary pieces from Tolkien himself - see The Vinyar Tengwar homepage for a list of contents for all the issues.
There are also many other gems on Lulu hidden amongst the more common vanity items. I found The Spanish Tolkien Society's journal Nolmë back issues available, Oliver Loo's A Tolkien English Glossary, and Quettar (published from 1980 to 1995 as the Bulletin of the Linguistic Fellowship of the Tolkien Society) in my brief browsing around this morning.
