“Is it worth it?”

“DC and Marvel editions at BooksEtc run up to 50% off RRP, and the same title can be £25 cheaper there than at another tracked retailer on the same day. One alert, one click, and months of subscription paid for in a single buy.”

Prices also shift within retailers. Whether it’s an omnibus, a compendium, or a hardcover, titles commonly restock at a reduced discount then drop back, a £10–25 difference on timing alone. D3-LZ catches those windows automatically, every few hours, across all formats. You decide whether to act.

Frequently Asked Questions

After checkout, you are redirected to Whop where you connect your Discord account. Once connected, your role is assigned automatically and you gain access to the subscriber alert channels. Completionist members can also configure My D3-LZ inside Discord for personalised DM alerts. The setup wizard walks you through it, and channel alerts are active in the meantime.

You can cancel your subscription at any time through the billing portal. Whop does not currently support direct upgrades or downgrades between tiers, so changing tier means cancelling your current plan and subscribing again to the tier you want. If you cancel during your first 14 days, you will not continue onto the paid monthly plan. If you cancel after paid billing has started, you’ll retain access until the end of your current cycle. You can access the billing portal directly at whop.com/@me/settings/orders.

Reader tier tracks BooksEtc only. Collector and Completionist tiers track BooksEtc, SpeedyHen, Scifier, and Reed Comics across 2,600+ catalogue books. We may expand retailer coverage over time.

Yes. Every subscription tier starts with a free trial for 14 days. You get access to the D3-LZ tracking service and the Discord alert channels for your chosen tier during the trial. If you keep the plan, it renews monthly at the listed price after the trial ends. You can cancel through Whop before the trial ends if you do not want to continue. If you cancel, you can still remain in the Discord server and take part in the community channels, but paid service and alert channel access ends when your trial or paid access expires.
