Well, It depends on the type of shipping method used and who you bought it from. Some people will use US mail, Fed-ex, or UPS. All three have an overnight service, but if you did not pay for that then it could take from 3-10 business days (Mon-Fri), sometimes even longer (7-14 days). When I used to order books off of ebay they used to arrive within a week (or 7 buissness days to be more specific), but every once and awhile you will get a book that takes longer. It will also take a different amount of time depending on how close you live to where the books are being shipped from. If you live in the same state, or close to it, it might take less time than if you live across the country or in another country (sometimes the seller will specify where they are shipping from). The time may also very depending on weather you bought the manga from a company or a personal seller. The company will usually specify that they ship the product within a day or two (buissness days) of purchase (in other words they put it in the mail, not that it will get to you), but a personal seller may take longer. Also, look on the page that you ordered the books from, it should say under the shipping the cost the shipping service and the estimated time. You can find the shipping information at the top of the page near the cost of the shipping under the bidding information. I hope this helps.
When something is shipped from Japan, again, the time depends on the shipping method. From what I have read, if it is being shipped through EMS is can take 4-5 days, but some others like Fedex or DHL may take longer. Also, in case of parcel, it may take more time (10 to 14 days) or it may take less time if you payed for a faster shipping method. It also depends on the seller. Many companies in Japan on ebay (that ship to the US) say that they will ship (mail it out) with 3 days of recieving a payment, so that also needs to be calculated for. But, from what I have heard, shipping something from Japan to the US does not take as long as one might think (could be around 5-7 days).
