Sent: 3rd Dec
First offer: 11th Dec - 8 days later (from East Anglia)
But since received all the others (not all offers, but replies all the same), and all by 11th Jan.
The rest came in very quickly on 4th, 8th, 9th and finally 11th of Jan. Wierd.
One of the quickest times in which all 5 have been received I reckon...
