You can now run a promotion straight off a page URL. Point a QR code, a flyer, an ad, or an email link at one of your page builder pages, and the discount is already applied by the time someone signs up. They don't type a code, they don't hunt for a box to check. They land, they sign up, the deal is on.
The trick is a code in the link. Add ?code=YOURCODE to the end of any page builder page URL and that code rides along and auto applies at signup. Because the code lives in the link, one page can run a bunch of promotions at once. Give each source its own code and your reports tell you exactly who sent the signups:
Same page, different links.
To make it land for the customer, there's a new block called Promo Code Unlocked. Drop it anywhere on a page and it shows a banner with the real offer, "20% OFF" or "$10 OFF" or whatever the promo is named, plus a note that it's applied automatically with no code to enter. Best part, it only appears when the visitor actually has a code. No code, no banner, so it's safe to leave on any page and it just lights up for people who followed a promo link.

There's also an Auto-set pickup location option in a page's Settings if you run pickup spots or co-ops. Pick a location and anyone who signs up from that page lands right on it, shared address and schedule and all, skipping the home delivery step. Handy for an employer, a gym, a school, or a neighborhood pickup, paired with its own code so you can track it.
Set it up once and reuse it forever. Seasonal sales, partner deals, event signups, a code on a postcard, whatever you dream up. Make a page, add the block, put the code in the link, and share it.
