I've come to rely upon Buyee when trying to purchase hard-to-find items from anime series that are not current. Being able to buy from a wide range of websites, and be able to add them with the "Add to Cart" function from the Buyee Chrome extension makes things super convenient. I think that at times it can be hard to understand which fees will end up actually apply - they obviously give you many warnings about possible fees (domestic shipping, purchase fees, etc.), but I sometimes feel I won't really know how much something is going to cost me until I actually have already purchased it. The fees can be a tad steep - they really add up - but honestly for the service you are getting they make sense. Would recommend.
