If you look on pixel-offers.com/bose it states that Vodafone and Google Store are the only qualified shops in Ireland. Whether they would reject an Amazon receipt I don't know.
On the Amazon site it quite clearly says UK only, so it's a risk. They may not deliver to Ireland if the seller was Amazon and they may not accept parcel forwarding services as a valid address.
Hopefully all will be OK though.
But Google, please release some stock to your Irish store!
