As this thread is the first one that came up on the Google search and I've just dropped my film off, I thought I'd sign up to update this thread.

I had 5 rolls of Boots process-paid film to develop and was going to post them, but coincidentally had co come to Warwick. Cewe accepted my films at the door and say they are still receiving thousands of rolls of E6 and C41 from (mostly) Boots and the work is stable (no sign at the moment of it going away.

They also handle any Jessops prepaid mailers, I understand.

They say they'll get my processed film posted back in 5-7 days.
