When email marketing frustrates you …..

I like Amazon's emails. They're usually nice and targetted and tell me about new products that I may be interested in buying. If I don't want to get them I can simply optout. So Amazon recently launched their Grocery Store on the .com site (I presume there'll be flavors (sic) for their other shopfronts at some point in the future).. and they've been pushing it hard ever since. Unfortunately they won't ship to Ireland... So why the hell are they teasing me with a $10 coupon?
