Amazon Prime Now is offering Cadbury Roses, 500g bag for £1.75.
Prime Now is an app. I've added a link to Amazon's instructions for downloading it. It's only available in certain parts of the country and this deal could only be available for those within delivery distance of the Birmingham warehouse.
Minimum order is £20.
Someone else posted a deal about 20mins back for Heroes 500g bag for £1.77. That deal was removed. I couldn't see Heroes available for me in the Birmingham area, but you might see these in other parts of the country.
