An advent calendar gives customers a reason to come back every day in December. With Sparkflow you create the calendar in the admin, fill each door with text, an image, a discount code and a link, and add the block in the theme editor without code. From the start date, one door opens each day. Up to 31 doors, in any order. Sparkflow creates the discount codes in Shopify, valid on the opening day. Afterwards you see which door was opened how often. Plus a countdown timer. Start now!

• Up to 31 doors, reordered by drag and drop, own column count on phones
• Opens to the day, with your own message for locked and missed doors
• Discount code per door, created in Shopify and valid on its opening day
• Per-door report: clicks, visitors and share of the whole calendar
• Countdown block, snow animation, custom CSS, English and German

Shopify's "one per customer" only counts accounts and emails. Anyone with a second email gets your welcome discount again and you never see it happen. OnceOnly first shows how much of it went to repeat buyers over 12 months. Then it recognises the same person behind a new email and address and rejects the protected code or lets it through and tags the order. No Shopify Plus required. Only checksums are stored, never plain text. Servers in the EU.
