Zenmarket is a great place to buy stuff from Japan. The fees are low and they do have promotions from time to time for various shops where you don't have to pay fees. One thing about Zenmarket I like is that they finally added Mercari to their list of shops they can acquire merchandise from. I love to collect anime related merchandise but much of it always seems to be listed on Mercari and Zenmarket only just recently added it, so I'm happy they finally did that. International shipping fees can vary depending on the shipping method used. I tend to use the least expensive one even if it takes longer to get to me.
