Well I can get the staff to drop post off at the post box, I think I also get close to a postbox when I go out for a walk with one of the carers from time to time, so yes if I had some post paid padded envelopes then I could send them. presumably that would depend on weight, but a PCB or 2 isn't much...
I think any post that gets sent out usually gets dropped in the box by the manager here, so if there's not too much I can get away with giving to them
I'm sure it can be worked out!
