To think if vouchers expire on the 31st I can spend them tomorrow?

[Ramena]

My Tesco vouchers expire on 31st August. Does that mean I have to spend them by midnight tonight? I.e. as soon as it becomes the 31st they expire? Or can I still spend them until midnight tomorrow, I.e. they expire at the end of the 31st?

They expire on the 31st…so you have until 11:59pm on the 31st to spend or whenever they close for business that day

Have they said you can't spend them? It's obvious you have until the end of day tomorrow whenever that is for the method you're spending them
