A self-inflicted problem

Recently, I have become obsessed with buying doujinshi online, but my impatience means the wait of using a proxy has been wearing on me. It's like a paradox. Most doujinshi in Japan are quite cheap, from what I've seen, but the cost of international shipping incentivizes making slightly larger/weightier purchases to make the price of shipping 'worth it', which means its best to buy a handful of doujinshi at once. This wouldn't inherently be bad, but as I have to use a proxy service to buy them, the proxy fees add up REALLY fast, as they're typically charged by individual item/listing.

I tell myself it'll be better once I get the backlog out of the way, but if anyone knows any good places to buy doujinshi, let me know.
