M & S Premium Club reward

Thank you very much for your helpful replies. It’s always good to know you’re not the only one having problems.

I did this the other day. At first it wouldn’t accept any vouchers, not even the in-date ones. I then discovered I was putting the code number into the wrong box, it should have gone into the lower of the two that come up. After I changed boxes, it worked perfectly.

I know this doesn't exactly answer your question but it may help.

To ensure you don’t miss out on spending your vouchers, all Premium Club and Premium Current Account vouchers with an expiry date between March and August 2020 have been extended until 31 March 2021. This includes hot drink vouchers, birthday gift, and your £10 M&S vouchers to spend on clothing, beauty, lingerie and home.
**We are in the process of communicating with customers to share the full details of these changes. You can continue to redeem your vouchers online at marksandspencer.com (where applicable).

Hi, I too had the same trouble yesterday. I was trying to use one that expired in July of this year and it wouldn't accept it, however I tried another that is due to expire in October and it went through. I did get an email explaining they were extending the spend time on vouchers but have no idea why the one due to expire soon wouldn't go through. Will try to look for email I got, if I find it I shall report back. Hope this helps a little.
