I e-mailed, and got a reply too. I said it was collection only, but (whilst I'm still annoyed because you're right, Six, they should have discussed this with me first) they've been a little bit sneaky...but this could turn out nicely for me.
They spotted that I was willing to shift the doors to London (I am; I'm going next week, my DH lives there) and realised that they live on my likely route down...(they gave me their postcode). They said if I could meet them at a service station on my way, they would pay me 'a premium' for that.
Is this super dodgy? I was willing to shift the doors to London anyway, and I will be going past service stations convenient for them. So it won't be putting me out too much, and would save me having spare doors hanging around in London until they come to get them.
If not dodgy, how much should I push for??
