Lulu Recommendations

Lulu often has coupons (check here & here) so you can get your RPG fix a bit cheaper than usual. But what to buy? Here’s a list of things that I like.
I recommend changing the LULU storefront to the US store (for USD) or the Ireland store (for €) because they have the best coupons.
I’m listing the paper book option, but sometimes there are ebooks or hardcovers available as well.

If you are interested in some more lists, check out Martin Ralya’s recommendations (OSR and other stuff), Tim Short’s list (OSR) or Wayne Rossi’s page (OSR).
