I'm in sheffield so too far away to help really.

Do you mean you'll have to carry the boxes of kitkats to the post office on your motobike?

If so just do one at a time.

People apreciate you are doing this out of kindness, and for no profit. So anything people can do they will to help i'm sure and no one will moan about waiting for deliverys.

To be honest, if it was me, i'd have put them on ebay, and made extra cash, (perk of the job).

What ever you choose to do mate.

Let us know.
