Q. I would like to watch more Blu-ray movies, but I can’t seem to rent them anywhere. There’s no Blockbuster, or anything! So I’ve been thinking about Redbox. But how does Redbox work? How do you get the discs from them? — Chi Chi, Marina Del Rey, California.

The Redbox kiosk looks basically like a soda vending machine and can be found in more than 41,000 locations across the country. The machine is quite easy to find once you go to one of the locations because of its bright red color.

The machine carries from one to a couple dozen copies of each movie advertised in the box. But not every box has every movie available from Redbox; for example, you might find the Blu-ray edition of A Quiet Place in one Redbox kiosk but not in the one a mile up the street.

To find out which movies each kiosk currently has, you can download a Redbox app on your smart phone or iPad that gives you an up-to-date inventory. I’ve used it and it’s very helpful. You can also check your local kiosk’s inventory by using Redbox’s web site and clicking on a movie that you want to rent. The site will tell you which kiosks have it in stock.

Now, what’s the price, you ask? To rent a DVD overnight, the cost is $1.75, which includes tax. To rent a Blu-ray movie, the cost is $2, which includes tax. The tax might vary slightly based on where you live. (Also, Redbox is now renting a few 4K titles in six test markets for $2.50 a night.)

You have until 9 p.m. the day after you rent the movie to return it. If you don’t return it by then, you will be charged for another day’s rental for each day the movie is out. If you don’t return it for 17 days, you will be charged the maximum price for a purchase ($34 for a Blu-ray and $25 for a DVD) and the disc is yours to keep.

(Note: You can return it to any Redbox kiosk in the United States, not just the one where you rented it.)

You are eligible to rent three different movies the first time you use a Redbox kiosk; after you’ve used it once, you can rent five different movies at a time.

You pay for the movie by using a credit card. But you can also go online at Redbox.com, set up an account and reserve your movie online. Then, when you go to the kiosk, you will touch the button that says, ‘Reservation Pickup.’ After that, you swipe the card you used to make the reservation and pick up your disc. (You can also make reservations using the Redbox app on your smart phone or tablet.)

Chi, Chi, hopes that helps. Happy Viewing!
