They are the gifts that keep on giving. DVD box sets provide hours, even days of entertainment, thanks to multiple discs crammed with bonus material, interactive features and extended movies, as well as fun collectibles and gadgets.

Though these gift sets have been fairly pricey in recent years, the home video industry seems to have caught onto the fact that not everyone can afford a $200 box set. Though some of the massive TV on DVD collections still hover in that price range, many others are half that or even less.

The best buy of the season: Look for the label “ultimate collector’s editions” (or “UCE”). These are cool gifts packed with extras and collectibles. Best of all, they have a budget-friendly price and offer a wide range of titles to please everyone on your gift list –from teens (“I Am Legend”) to hubby (“JFK”) and grandparents (“How the West Was Won,” “The Rat Pack”).

A prime example is the gorgeous “Casablanca: Ultimate Collector’s Edition” available Tuesday from Warner Bros. From the intricate laser-cut Moroccan design that slips over the sturdy blue box encasing the set, this is a beauty both in quality and price ($59.98 standard DVD or $64.99 Blu-ray).

The three-disc DVD has hours of bonus features and includes the bonus disc, “Jack L. Warner: The Last Mogul.” Also included are a lovely hardcover book; 10 oversized color postcards; copies of Warner Bros. correspondence; and a copy of the passport for the character of Victor Laszlo. Even more fun: a “Casablanca” passport cover and luggage tag to use.

Here are other ideas for all budgets and interests. All sets are available now unless noted.

“Alfred Hitchcock Premiere Collection” (eight discs, $119.98, MGM).

Also included: “The Paradine Case,” “Spellbound,” “Notorious,” “Sabotage,” “Lifeboat,” “Young and Innocent,” and the 1927 silent film “The Lodger,” considered to be the first true Hitchcockian film.
