They don't have everything when it comes to tech or more niche material, but Kenny's (https://www.kennys.ie/) is very good and offers free (and often fast) shipping.
That also looks like a good alternative for the EU and some other countries, with delivery at €1 per book. (Just not the USA, which is €9.50 for some reason.)
