When setting up a discount code, you can now allow your customers to redeem a discount code more than once - on more than one booking - along side setting how many people in total should be allowed to redeem the code.
Remember: customers on Baluu can only use one code at a time when checking out - this feature does not allow customers to apply multiple discounts on one checkout. It allows them to use a discount code on more than one transaction, should you wish to allow it.
How to setup multi-redepmtion
Head to Services > Discounts and click 'New Code'
On the popup which follows you can use the 'number of uses per customer' field to set a limit, or indeed allow a cusotmer who has the code to use it, an unlimited number of times.
You can then change this at any time once the code is live.
