I've done the run out to Richmond by transit and it takes about three hours, one way! Driving is more reasonable.
However, it is possible to send the cultures via Parcel Post. For two day delivery the cost would be $10 -$15, possibly somewhat less. Alternatively, I will be doing a trade with someone in Surrey in the next week or two; I could ask him if he would take the cultures with him and have you pick them up in Surrey.
I apologise for missing the question in your first post... I'm a home based hobbiest who grows live food cultures for my own fiish. I've downsized and grow a little more of these cultures than can be used. As for shelf life, I can pack the cultures with that in mind. They will need to be kept warm, of course, and level.
If we prearrange, pick up is fine up to ten thirty pm.
