I ordered some address labels for parcels from Amazon, and decided to order something together with it (that I had been planning to get sooner or later anyway) in order to take advantage of the "free shipping for orders over €20" offer they have.
After having a look through my wishlist and reading some of the reviews, I settled on a minigrammar and a dictionary of Ancient Greek.
Labels and books arrived today, so I have some reference material for Ancient Greek now. Whee!
(Well, I already had a grammar—in Modern Greek; a school textbook—and at one point during my mission I had an Ancient Greek–French dictionary that a missionary's parents had sent to her not knowing it was Ancient Greek rather than Modern and which she gave to me, but I left it somewhere during a move since it wouldn't fit in my luggage.)
Also, this puts me one step closer to my potential Ancient-Greek-like-Polish and Ancient-Greek-like-German conlangs (one reason, besides inertia, that I hadn't done anything with them is that my knowledge of and resources for Ancient Greek are too few and it would probably end up looking too much like Modern Greek, as I saw while developing Greek Sans Flexions).
