  • Need help with international shipping.
    I've used a few over the years but lately https://opas.com/ has been my go to. Really fast service, easy to use UI with multiple shipping options (depending on destination). From a cursory look they seem to ship to Japan. Source: almost 4 years ago
  • Where do you get original parts that ship online and legit?
    Try opas.com, a forwarding service that gives you a US address to order to. Cannot guarantee that they service Israel (I am in Sweden), but should do. Worked like a charm for me to get hold of a rare spare part for an old outboard motor... Source: about 4 years ago
  • Is YouShop in fact the cheapest USA-to-NZ shipping forwarder?
    I really rate OPAS (referral link, non referral link here). Multiple shipping options, fewer restrictions (Youshop won't handle Li-Ion batteries) and you get 20% off your first shipment. Source: about 4 years ago
