After November 1st, when you shop at stores without limits, your cashback earnings at these stores will affect your 30 day rolling limits. For example if you've earned €3,50 through a store without limits, this amount is deducted from your 30-day rolling autoreward limit.
If you had a total limit of €5 and no prior transactions, this will leave you with €1,50 for other limited Auto Rewards. If you earn €1,50 (3 x €0,50) from other stores, your 30-day limit is considered "full," and new transactions from limited Auto Reward shops will not earn additional cashback.
No worries, you still have the opportunity to earn Auto Rewards to all other stores that are not limited.
