Halloween welcome discount popups

Two to three weeks before October 31 for costume, candy and decor stores; one week is enough elsewhere. End them the day after Halloween.

Choose the dose: a full theme suits playful brands, a single seasonal accent such as a color or an icon keeps a premium store on-brand.

Most stores start at 10% off the first order or free shipping. Test a second variant before going higher: a bigger number rarely doubles signups, but it always costs margin on every first order.

After the visitor has seen enough to care: a few seconds in, after scrolling, or on exit intent. Showing it the instant someone lands from search on mobile is what search engines treat as an intrusive interstitial.
