Answer
VoucherBook automatically rolls active coupon listings to the last day of the current month. Always verify the promotion on the retailer website because a retailer can change or end an offer earlier.
The month-end date is a catalogue-management date, not a retailer guarantee. Retailer terms, exclusions and checkout eligibility always take priority.
What to check before checkout
Read the retailer’s current promotion terms, confirm that the code applies to the items in your basket, and make sure the expected saving appears before you pay.
