After looking through items... it seems as though some of the bigger lots of PC Engine HU Cards are what I consider to be the best buys. For instance: a lot of 105 PC engine cards on ebay went for $360 last week. The week prior to that the same people sold a lot of 105 PC engine cards for over $500. All loose. No sleeves, cases, nothing.
Yet... a lot of 40 seems to go for around $40 US dollars. Add in $5 for service fees... and whatever... plus more shipping.... it seems like a better bargain.
$1 a game is a lot better then $6 or 7 a game on an average.
So here in lies the problem. I deal through SMJ as well and they provide a fantastic service.
BUT.
To make it work, you really need volume and a decerning eye. A lot of stuff actually isn't worth it in the long run. Let me give you some breakdowns:
If an auction ends at 2000 yen or less:
~$18 for the item itself
$5 service fee
$2.50 bank transfer fee
~$5 shipping within Japan
~$10-20 to ship to the US or to the SMJ site in the US and then to you
= $40+ for an item at 2000 yen
An item ending 2001-4000 yen is $8. 4001-10000 is $12. And over 10000 yen add $1 per 1000 yen.
So what does that mean? Buying bigger lots is much much better in terms of distributing the fees over you items. That much probably seems obvious. But beyond that, and how I'm able to sell stuff relatively cheap here and still make a tiny bit: overall volume.
I regularly scour Yahoo JP for lots and in particular ones with systems involved. Why? Because I can mod the system, sell it at a reasonable price, and sell off the games at around break even or a bit over (~10-20%). Plus I fill holes in my own collection in the process. But I also have SMJ ship stuff directly to me by Surface Mail once they can fill a relatively large box. So I can squeeze about 4 bigger auctions of stuff into a box that costs $80-90 to ship, even though it takes 5 weeks to arrive. Once you're already paying to ship, it's less to make the box bigger, just like any mailing you'd do in the US too.
Again, this is how I can sell off games at $1 each and not lose money of them (generally). That's also why I ask for PayPal fees on stuff, since I barely break even on the cheaper games.
So don't go screwing me on those auctions you bastards.
