$12.97, but if they stuff a lot of packaging material in it could easily end up as $21.98.Don't forget the postage as well, it's about $12 (I think) with rightstuf while it'll be cheaper with UP1USA as it's shipped from the UK.
Wowhd is the future for Fumination Sentai and discotek. They are usually cheaper, no shipping or import fees. UP1 are still the go to for Aniplex releases.
Rightstuff do have a more extensive catalogue if your after older more obscure releases.
I've ordered several sets including the Danmachi CE all arrived within 8 days and no issues. Others on the forum have used them as well. I ordered a bog standard release to try them out first.Hmm, they do seem to be cheaper for things I've just had or are due shortly. Have they been around long, and are they reliable?
I will say one plus for up1 is I already have Umaru in my hands, 2+ weeks before it's official release date, though Wowhd seem to be offering it for a good £10+ cheaper. Other items seem a bit closer in price.
