Amazon's stellar promotion on 4K Blu-rays ends this weekend, so you're running out of time to take advantage of one of the best Blu-ray sales of the year. Make sure to check it out before May 27 at 12 AM PT / 3 AM ET.

The 4K Blu-ray sale gets you three movies of your choice for $33. You'll need to get three to nab the full discount, which is applied in your cart when you go to check out. All the movies are also Prime-eligible, which means you can get them shipped pretty quickly if you've got a movie night to set up. With the promotion, you're ultimately paying only $11 for each movie--and you can buy multiple sets of three. Considering many of these movies still routinely sell for $20-$30 (or more), this is quite the deal.
