By Right of Purchase is a 1918 American silent drama film starring Norma Talmadge in a story produced by her husband Joseph Schenck.

An up-and-coming actress and soon to be gossip columnist Hedda Hopper has a small role in this picture.

As described in a film magazine,[1] against the promptings of her heart, Margot Hughes (Talmadge) marries Chadwick Himes (O'Brien) and completely ignores the fact that her husband is very much in love with her.

There is a decided breach between them and when Margot takes up with Dick Derwent (Courtleigh), even though her husband forbids it, they break altogether.

The film survives today in the Library of Congress, albeit with some reported deterioration in the sixth and last reel.
