Merry Kissmas at Weirs. Weir & Sons’ Giant Mistletoe has become synonymous with Christmas on Grafton St. Each year, friends and couples grab their loved ones and share a kiss under the mistletoe and on social media for their chance to win a €1,000 Weir & Sons voucher. This year Sipit helped promote the giveaway by running cups with the popular Dublin café Coffee angel. Sipit also created a video for Weir & Sons about the partnership and giveaway, which was shared on social media by the client and café partner.
