Snuff shops in Scotland/Ireland

1

My Aunt and Uncle are traveling to Scotland and Ireland later this month and I’m trying to find out if anyone knows of specific locations of Tobacconists that sell snuff. If anyone knows of one that sells any exclusive Scottish/Irish brands of snuff that would be ideal. I’m going to send them a check before they leave the US and they said they’ll pick up some snuff and bring it back for me. If anyone knows any shops please post the address or at least the name of the shop and city/town/country they are in. Thanks everyone.
