Amiami is my preferred store. (dozens of purchases vs two)
Because of the sale, I compared items on my watch list from Amico to TOM.
Converting from JPY to USD, the after discount prices on what I was interested in were all lower on TOM.
The cost of the three scales that I decided on was about $100 less before points and shipping.
An average of 17% cheaper.
Shipping is free from TOM, but releases are usually delayed a month or two.
Since they weren't day-one purchases that I was on the fence about anyway, I don't mind the longer wait.
