Back in August Revive Bookstore and Coffee Shop opened at 57-59 Castle Street in Comber. Not only can you enjoy a good cup of coffee there, and perhaps even a soda farl, but you can also pick up a copy of "Soda Farls and Redemption Songs"! They also have a new online shop which you can visit here at ReviveBooks.com and a blog you can visit here.
If Comber's too far away for you, try Ards Evangelical Bookshop in Newtownards who also offer online shopping, and a number of other shops across Northern Ireland.
