You can now create a link in bio page with Checkout Page. It lists your checkout pages, events and forms, and keeps your upcoming events current. And the best part? It's 100% free. Link in the comments.

Give your AI agent 132 pricing and conversion rules. We released 19 open-source (MIT) skills. Most rules cite a peer-reviewed study. Rules without one are marked as practitioner tips. Works in Claude Code, Cursor and Codex. github.com/checkout-page/eco…

An empty promo code box makes people feel they are overpaying. In a checkout study, shoppers with no code rated the price as less fair and fewer completed the purchase. (Oliver & Shor, 2003) 1 of 132 rules in ecommerce-skills, free for your AI agent: github.com/checkout-page/eco…

Ever had a form tell you "invalid email" while you were still typing it? In two studies, instant errors were the worst option: people ignored them. Errors shown after the form was complete worked best. (Bargas-Avila et al., 2007) From ecommerce-skills: github.com/checkout-page/eco…

Ever picked the unlimited plan when pay-as-you-go was cheaper for you? Professional buyers do it too. They chose a flat rate that cost 20% more than paying per use. (Journal of Business Research, 2021) From ecommerce-skills, free for your AI agent: github.com/checkout-page/eco…

A bank raised its referral reward from €20 to €50. Referrals went up. Profit went down. The customers it brought in were 48% less profitable on average. (Marketing Science, 2020) 1 of 132 rules in ecommerce-skills, free for your AI agent: github.com/checkout-page/eco…

Ever looked at a $39 plan and a $48 plan and thought the upgrade wasn't worth it? At $40 and $48 it feels closer. When the first digit changes, the jump feels bigger and fewer people upgrade. (Journal of Consumer Research, 2021) From ecommerce-skills: github.com/checkout-page/eco…

Tell people what their friend gets, not what they get. Referrals went up 86%. Found in two field experiments (Information Systems Research, 2020). The referrer still gets a reward. From the /referrals skill in ecommerce-skills, free for your AI agent: github.com/checkout-page/eco…

Ever get a cart reminder minutes after you closed the tab, and it annoys the hell out of you? It also fails. Within an hour, a reminder made people buy less than none. After 24-72 hours it worked. (Journal of Marketing, 2020) From ecommerce-skills: github.com/checkout-page/eco…

We open-sourced 19 agent skills for ecommerce pricing, discounts, checkout and product pages. They are based on research. Most of the 132 rules cite a peer-reviewed study. Use them to set a price, word a discount or audit a page. npx skills add checkout-page/ecommerce-skills

Deep discounts can backfire. In daily-deal markets, deeper discounts sold less, because a big cut reads as a quality problem. The discounts skill warns you above 40% and suggests a gift or bundle. Clearance with a stated reason is the exception.
