Ok this I believe is the cheapest and EASIEST way to get pre-ordered eroge (i.e. new & dispatched on release day). It’s via amiami.com. [amiami]
Based on the average weight of 600grams per boxed copy. Please select SAL (unregistered) for 6-13 days delivery. Works out at 1040 yen per kilogram i.e $8 per game. For other services, please use this tool. The reason why it is so cheap is because we are abusing the Small Package service, the cheapest in existence (thanks to @jyuichi for the info). There is Sea mail which is half that price. You must pay by Credit Card. If you want limited editions, please adjust for additional weight accordingly.
“Here is where I need some help – I need confirmation. Unfortunately normally I would just do the research myself and then write it up here, but thanks to Yodobashi.com’s hetare, that is not possible for the mean time. Amiami has a number of items up for cheap. Pick one and see if they send it to you. If they don’t, then they will just refund straight away.” Thank you.
Do note that if you select English user interface up at the top, their catalogue shrinks. So it is better to use the Japanese site Amiami.jp. Also Amiami tokuten is quite weak. If you are willing to pay the ‘much larger prices’ for Sofmap and Getchu tokuten, then you will need to use Tenso.com or Yokatta Shopping Service. Note for older releases, amazon.co.jp, sofmap or suruga-ya will always be cheaper.
In the future I will write a comprehensive guide to shopping for eroge. For now you can refer to relentlessflame’s guides and merry x’mas peoples! And yes it is true I’ve been spending less time on this blog, that is because I’ve been working on a secret project :3
