If anyone here has an open proxy on ZenMarket, there’s a shipping discount presently in play (available to select countries). But it runs to only to February 25th. I’m in the USA and it was valid for me. You can save “up to 52%” with “Lucky25” as the coupon code. I just had one with an initial shipping cost of ¥3180, and it got slashed to ¥1438.
The trick is, your packing has to finish by Feb 25th, because when making payment the coupon code ends on that day. So, now is the time if you’ve got an open proxy!
