The title of this should really be the complete Marvelettes 1961-1966. It includes their first four studio albums, a live album and all of their non-LP A/B-sides. All tracks have been remastered as well.
The label is Hip-O Select, and the cd is limited to 5000 non-numbered copies. In the US this cd is going for between $36 to $40 (which is more than £20), making this import price an absolute bargain. Considering that some Hip-O select sets go for ridiculous prices once sold out (for example last year's Four Tops Lost and Found cd is on Amazon markeplace for £75!) it's worth getting even if you are not a big Marvelettes fan.
