Purchase a subscription using Paypal or debit/credit card
All subscriptions have an end date. If you subscribe partway through the year, I'll make sure you get access you the puzzles that you missed through a Google Group. Your subscription will not be renewed automatically, but you will receive an email reminder about renewal near the end of the subscription period.
If you regularly co-solve with a friend or family member, it's fine to buy one subscription for the pair of you. You should also feel free to share a puzzle or two with a friend who might enjoy it, but please don't post these puzzles in public or on social media. You can also buy a gift subscription for somebody (whether or not you are a subscriber yourself); contact us for more information about that.
