It didn't occur to me to be shopping on Japanese Amazon for old games.. I thought I might have searched before but I guess I was mistaken! Are there deals to be had here? I could do my last minute shopping here!
Interesting.. interesting indeed.
update: ooooh ho ho.. I couldn't resist, so I went ahead and ordered about 10 games I've been needing... Also got a Solomon's Key 2, so thank you for pointing that out for me, Manuel!

Got most of the games in the mail already!
And ain't it wonderful, they're in great shape! Yeah, I had to pay shipping, which was often more than the price of the games themselves, but I'd say a good looking cartridge (some of these even came in boxes) is well worth the 400-800 yen I payed for them, particularly since I couldn't find them literally anywhere within 50 miles (well at least at the shops I know about)
Bionic Commando.. Just the cartridge, wonderful condition for just a cart... 820 yen total. That sure beats the 3,000yen for a dirty one I saw once in Osaka.
I'm sure if I saw any of these in the stores (one or two of them I had) they would be more than the total, plus shipping.. Thanks again for the tip Manuel.
