I'm a regular at Amiami. The points I collected for nearly a year,converted it to lessen the cost of the figure. I'm not sure how their system works but since I live in S.E.A.,I opted for SAL Parcel, which they allowed. It's got some tracking but not as expensive as EMS. received it after 10 days. Since you live in the continental USA, maybe EMS is automatic?
In as much as I don't want to badmouth hobbysearch, (as I also purchase from them if amiami is sold out), now that's were wallet rape begins. They had a sale once on a figure, Kaitendo QB Nanael, about 50% off..........but they didn't allow SAL parcel, it was automatic EMS. That fig btw ain't half as big as Sheryl............more like a fourth the size of the box and still charged EMS. Ouch!
I have ordered in the last 5 years as an online customer 3 SAL Parcels, Encore 20A, Sheryl Nome (very big alright) and a Daiki figure at 1/5 scale. Well, size and weight was justifiable on all three.
As for customer support, mixed bag in that there's one who is kind of okay when responding ( I believe he is an American) while another responds like a brick (must be Japanese).
