**** dude. That is along time. Ive seen people who ordered theirs in November getting theirs now. Maybe shipping to Ireland takes a year? I have no idea as im in the states but that would be insane if so. I would call Apple right away, because that has been a long time, especially for a base model M1. I would maybe go to the nearest Best Buy or computer store (im not sure if they have them in Ireland) and buy them as stores have the base models in stock, just not the upgraded configurations
****EDIT ***
Just realized you guys not in the united states write your Dates differently and switch the month and day compared to how we do it in the states. NOW i get it lol. Yes that should be normal delivery time, but i would check your local computer stores because the BASE spec M1's are in stores
