Bundle of Holding for Trail of Cthulhu 1E (second edition is in development though the blog mentions 1E supplements are "wholly compatible" with 2E). Includes titles from six previous bundles and three products not seen before in Bundle of Holding, though still a far from complete 1E collection (although to be fair Pelgrane does a lot of taking individually released PDF adventures and bundling them into a book).

For the variably increasing $37 price you get:

• PELG-T01 Trail of Cthulhu (2008) [OWN]
• PELG-T04 Keeper's Resource Book and Screen (2008) [OWN]
• PELG-T06 Shadows Over Filmland (2008) - 11 shorter adventures [OWN]

I own a surprising amount of this already. Certainly not enough new stuff to warrant buying this bundle.
