Common Questions
How does the purchase-to-entry work?
By default, every $1 leads to 1 entry, but you can customize this (e.g. $10 = 1 entry). The system calculates entries automatically based on order value.
Is this legal?
Yes. We support "No Purchase Necessary" (AMOE) methods where required by law, ensuring your sweepstakes are fully compliant with regulations.
Does it work with subscriptions?
Absolutely. We integrate seamlessly with Recharge and other subscription apps to award entries for recurring orders.
