I'm sorry but you've really fecked me off! You time waster.
*Day 1* "Thanks for the email on the refurbed base unit for £200 leave it with me."
*Day 2* "These refubed ipads for £150 do you have them? Oh, you order them in. Let me think about it."
*Day 3* "How much for a Samsung 10.1?"
Why do I say time waster? £200 is clearly too much for him, £150 was probably too much for him and now he's taking the piss by asking about something that is clearly double the price of second hand equipment.
