This information is kinda nerdy but while shopping online for anime stuffs from sites that only accept payment in yen like Hobby Link Japan, I tried to use the best payment options available. Most credit cards charge around a 3% currency exchage fee (ex. $100 charged on a card, fee = $3).
Instead of calling each of my credit card companies to ask them about charges in foreign currency I found this article:

If you compare the bullet "Credit card purchase:" by each credit card issuer you will notice that Capital One has a 0% charge. I have confirmed on my Wells Fargo card that they charge a 3% currency conversion fee and I called Capital One (since I have this card also) and they confirmed that there is NO currency conversion fees (as of the date of this posting) or additional fees charged to the card.
Another payment option that was available was Paypal. Usually Paypal will exchange currency at the current exchange rate but will ultimately charge the seller around 3.8% of the transaction's total as a fee which the seller may pass along to the buyer. I'm not sure if Hobby Link Japan does this.
I have also noticed that buying anime stuffs is like the stock market. The exchange rates between the U.S. dollar and Japanese yen may fluctuate daily with trends upwards or downwards and "timing the market" comes into play.
here's a link to illustrate historical daily exchage rates:
