There is now NO LIMIT on the total number of rewards you can add per order.
The limit has been revised to select items. There is a max of 2 Mystery Bath Bombs and 2 Mystery candles that can be redeemed per order (total of 4 free products). All other items are unlimited.
Please understand that by implementing these limits, it allows these mystery product rewards to be available for more customers and keeps us from needing to raise the points required to redeem them.
