Who sets the prices for each country? Is this coordinated in Japan? I think it has to be because I noticed that the price increase on Butterfly NA site increased several days before Megaspin. I bought two sheets from Megaspin at the old price on September 23, total price about $135 for the two, free shipping, and the price at that time was $150 on the Butterfly NA site. I checked both because I obviously was looking for a cheaper price. But when I checked just now on Megaspin, the price was increased to $150 for two sheets. In other words, it took Megaspin a couple of days to raise their prices, after Butterfly NA. It seems most likely to me that that the Butterfly dealer in this case (Go Table Tennis, one of the several vendors who sells their stuff on Megaspin) received a directive from Japan to do this, and they have to comply if they wish to continue to sell their products (a feature of dealing with Butterfly that I know is true because vendors have told me this is part of the deal). It seems unlikely that they received new stock between Sept 23 and Sept 25 at a higher cost that they in turn had to recoup.
