Looking for that last minute gift and run out of ideas? You can get a £25 M&S or Argos Gift Card for £20 at the O2 Gift Card Store!
Just add you chosen £25 gift card to your online basket, and use the code Priority125 to get a discount on the M&S card, or Priority225 for Argos.
You can get the codes digitally so there's no need to wait for a physical card to be delivered so you will be getting it in time for Christmas.
It looks like it's limited to three per customer as no one has had any luck buying more than that.
Although you are getting a digital code to use as your voucher the O2 website says that you can also use the codes in store as well, presumably by quoting them to the cashier.
If you were needing that last minute emergency gift or looking for a way of bringing down the price of something you were planing to buy then this could save you a nice 20%.
