I honestly don't know...SAL is funny like that If you're in the US it could take up to a month for delivery. I live on the westcoast (and just 2 and a half hours from Los Angeles) and it takes up to a month for me to recieve my order. For some products, EMS is actually cheaper than SAL.
After looking at HLJ, it looks like EMS and SAL are pretty even...there's only a few dollars difference between the two...
EMS: 5,400 yen, SAL: 5,000yen
There's the shipping estimate HLJ gives for the PG Strike Gundam.
I could understand you using SAL since HLJ didn't give any cules to shipping. I feel for you though. When you try to get something you've waited for so long and when it's finally in your grasp, stuff like this happens...
