Hi Noel,
Yes, people who selected for 'Exhibtion/Show Pick-up' email us at info[at]irishrailwaymodels.com and request a postage quote. If you would like to change your delivery option from exhibition pick-up to post/courier, get in touch and we will organise for you to pay the additional cost through our online facility.
As for your second query it's too early to confirm but it is what we'll be aiming to do. Please remember that we are doing this in our spare time, we will be checking each box for QC issues and signing them off for dispatch too so it will take a little while to work through the back log. We literally have hundreds of parcels and orders to organise! It will be done on a 'first order, first delivery' basis with the earliest customers getting their packs posted or dropped to them first.
We will also be contacting those with outstanding payments in the coming days to complete their purchases.
