It was a mistake and a glitch in there matrix it was genuine. We just sent you an email that looked like it didn't come from us, sorry about that, there was a glitch in the matrix! Here's the email again, just in case.
Thanks for this, I checked and I have it. The only thing I would note is that, rather than being from the normal firstname.lastname@example.org, this email is from email@example.com. Just wary, as I went through a phase of getting loads of spam from a seemingly genuine Argos account.

Burgers are tasty from there. I use tastecard to get 2for1 starters also
