Got a bunch of Super Famicom games in the mail! Highlights: Yoshi's Island, Super Mario Kart, Front Mission: Gun Hazard, Harvest Moon, Panel de Pon, and Bahamut Lagoon.
As it turns out, if you aren't concerned about the language barrier (mostly an issue with RPGs) and have access to a good proxy service, most SFC games end up being significantly cheaper to import than their SNES equivalents are to purchase domestically. I got thirteen cartridges (around the sweet spot for weight for a single box to still be eligible for cheap shipping) and paid $75 total; Harvest Moon alone would've cost around that if I had purchased a US cartridge, and wouldn't have included Japanese Kit Kats.
My next order will most likely include Super Metroid, Super Castlevania IV, the various Kirby games (except Kirby's Star Stacker because I can't find any SFC copies), Super Puyo Puyo Tsuu Remix, Pocky & Rocky, Popful Mail, all three SFC Parodius games, and both SFC TwinBee games. Six of those games cost $20+ each on eBay for bare cartridges (or, for Popful Mail, $70+ for just the CD), but for import copies of all of them together (including shipping and proxy fees), I'd only pay ~$120 total.
