First of all, tradedoubler already have.
Second of all, as an affiliate that does ... let's say "pretty high volume", I stay completely out of Ireland.
10,000 conversions @ €20 CPA trumps 1000 conversions @ €100
Quite simply, there is no volume in Ireland. The companies that do offer programs already have massive budgets and are pretty much "in" every nook and cranny that you can think of.
