Discount codes
A real code, made in your Shopify admin
You set the percent. When a form gives a code, Castor creates a one-use Shopify discount and shows it to the shopper on the spot.
- One code per signup, so it cannot be shared around
- Every code listed under Discounts in Shopify
- Shown to the shopper the moment they sign up
Kind on phones
Never covers the page on arrival
On phones, popups wait for a scroll or a few seconds and fit the screen, in line with Google's advice on intrusive popups.
- Close button on every popup
- Stays away for the time you set after it is closed
- Once per visit or per day, your choice

Sample dataQuestions about Popups
Will popups annoy my shoppers?
Castor is built to ask once. Each popup has a close button, stays away for the time you set after it is closed, and waits for a scroll on phones so the page is never covered on arrival.
Does it work with my theme?
Castor works with Online Store 2.0 themes, which covers Dawn and the free Shopify themes plus most paid ones. Popups load through a theme app embed you switch on once.
Do popups show in my shopper's language?
Yes. If you sell in more than one language with Shopify Markets, add a translation and Castor shows it to shoppers browsing in that language.
