I just realised that if I want to do Prime I have to use the "Buy Shipping" button within Amazon, eeven though I am only shipping with Royal Mail.

I have been sending using Click & Drop on a T24 service. So after being threatend to be taken off of prime, I have started to use Buy Shipping. I now have have 50+ parcels that need to be collected or dropped off somewhere for delivery tomorrow.

Where can i drop them off, the Post Office wont take them without a manifest

Amazon have stopped collecting from me because I started using Royal Mail.
