The hyper-deflation of entertainment products online this holiday season is now moving to brick and mortar.  Target will be selling The Dark Knight DVD, originally released last year, at $3.99.  Other $3.99 titles are older:  Elf, Sex and the City, and Forgetting Sarah Marshall.  The Dark Knight Blu-ray and others are $12.99. 


Other films range from $5.99 to $10.0, including fairly recent animated releases. 


TV season sets, including Supernatural, will be as low as $8.99.


Major retailers have made entertainment products a battleground of price-cutting this holiday season, with advance order hardcovers under $9.00 (see “Online Book Price Wars”) and advance order DVDs under $10 (see “Walmart Opens New Front in Online Price War”).
