This is not going to be fun for Ireland. Ireland doesn't have its own regional Amazon, but the UK one would have great fast shipping. I wonder if shipping from Amazon DE or FR will be more popular in the future.
This switch was done to a number of other European countries within the last decade (inc. Finland).
edit: OTOH, I just realized Ireland uses the UK electrical plug, which complicates buying electric stuff from amazon.de a bit...
Maybe asking a friend in Belfast to forward a parcel to Dublin will continue without any checks, but a parcel forwarding service is unlikely to go unnoticed.
