(CNN) —  

Amazon’s subscription box service is quite literally a gift that keeps on giving, and just in time for Valentine’s Day, the mega-retailer is offering up to 50% off the first box from a subscription series for a limited time.

Subscription boxes are available in a variety of themes, from chemistry sets so kids can (safely) conduct their own experiments to self-care boxes and tea subscriptions that introduce you to loose-leaf tea from around the world. There’s just one catch: The savings are only open to first-time subscribers, so if you haven’t tried one of these yet, this is the deal for you.

With savings of up to around $25 on some boxes, there’s never been a better time to try them. Plus, you’re not locked into a time frame with these subscriptions; you can cancel anytime. Read on for some of our favorite Amazon subscription box deals below, any of which would make a delightful Valentine’s Day gift for the loved one in your life.
