Hi, the same happened to me.
I did not proceed with the transaction as I had my doubts.

I was selling a phone and the e mail response said he was buying it for a friend as a gift.
His e mail was weird as it was written in such a way almost as if he was desperate for me to agree to use PayPal.
I also received a similar e mail from a different e mail account and as with [email protected] I got a text first requesting I respond via e mail to: [email protected]. I suspect it's the same person/ people.
I was offered £30 extra for P&P but I felt that was suspicious as too good to be true, I wasn't having any of that.
I'm not being caught out by any low life.

I spoke with PayPal who advised this might be a scam. Be very careful.
