Amazon offers Prime members Sailor Moon R: The Movie on Blu-ray / DVD for $20.37 with free shipping. That's $5 under our March mention of a preorder and the lowest price we could find now by $5. This is a remastered, re-dubbed version of the classic anime film. (Japanese audio with English subtitles are also included, if you're a purist.)
Note: It's temporarily out of stock, but can still be ordered at this price for delivery when available.
