You can set your promotion price at any price you want between 50-89% off. We do not require a certain price to run a promotion with SixLeaf.
If you are looking for a maximum amount of codes taken every single day, the larger the discount, the better your code redemption results will be.
If you are following the SlingShot Strategy and not seeing the results you prefer, cancel your ongoing promotion and create a brand new promotion in SixLeaf with new codes from Seller Central with a larger discount. Request a copy of the SlingShot Strategy from Customer Support.
