In mid-December, I received the weekly advertising flyer of a local store chain. At the top, the flyer said "Christmas Sale".
If a sale is advertised like this, with the name of a non-Jewish religious holiday explicitly in the title, is it permissible to shop at the sale, and to benefit from the sale?
Please base your answer upon sources, and please cite them.

A question by DanF: "When a chain store adverises a 'Holiday' or 'End of Year' sale, may I buy their product?" DanF's question seems to be about stores which are less explicit in naming their sales.
