Depends on the proxy company you use, the two I like are White Rabbit Express and From Japan (the former costs a little more but has fantastic English customer support, the latter is cheaper but you're slightly more on your own). Generally all you do is copy the link to the store page ( https://sweeprecord.com/srns-2004/ ) into the order page (for FJ you copy it into the Find/Order/Bid box in the header), fill in a few details about exactly what you want to buy (price in Yen, product name in Japanese) to ensure they get the right thing, they'll quote you for the cost, you pay the service fee, they order it and then when it arrives you choose the shipping method and pay for the postage.For a first time proxy order I would probably recommend WRE over FJ since it's easier to follow, FJ is great for auction bidding though.
