free shipping over a certain amount spent is always attractive (and fixed fee for wall ireland not just ROI!)
special discount for beoir members is always appreciated!
Bonus bottles are always a nice touch
More important is to be fairly priced with a wide selection including as many ltd edtions as possible, if you can get stuff I can't get elsewhere (and a wide range of other stuff) I'm likely to use the service. I'm not loyalk to a single site and have used drinkstore, mchughs & bradleys in Ireland and ales by mail/brewdog, beer ritz, eebria & beer merchants in UK and even Belgiumbeerinabox all delivered to NI
