I don't buy eroge online, i ask my friend to buy it for me and bring it back when he is back frm Japan. You might want to ask Check since he buy a lot of things online.
I have a friend who is an expert(he imports bds, eroges and other merchandises) , did research on shipping and different sites, comparing prices but he is sorta busy and not online much nowadays.
^ This is basically the reason for me not trying to talk to him. He is in a really higher position. (Check and the others are too, but you guys talk (sometimes)) And besides, maybe he's busy doing something, i don't wnat to bother a higher-up with something like this. >_>"
Also..." Powered by Checkmate?" What do you mean by that? x.x
