Some of the emotes are a bit pricey given their simplicity. Others, however, I feel I can justify the $7 USD for, like the Eastern Dance and Play Dead. The former is extremely elaborate; and the latter is different across each race and gender. Eastern Stretch is probably also worth the $7 because, again, elaborate. I just don't like it, so I didn't buy it.

But Pretty Please, Eastern Bow, and Backflip are a bit pricey for what little they do. I'd suggest waiting for them to go on sale if you want them. They're optional, and they aren't going anywhere. And SE has sales at least twice a year for the Mogstation stuff.
