The retailer will employ a host of innovative social media tools to help encourage sharing and interaction as the battle for hearts and minds in the run-up to the biggest shopping period of the year becomes increasingly digital. These include a tie-up with Snapchat, which will allow UK users of the messaging app to use a Buster lens on Thursday, so they can snap portraits with comedy dog ears and nose. After that, the filter will pop up when Snapchat is used in a John Lewis store. Until Sunday 13 November, customers will be able to use special Twitter stickers that pop up when they use the hashtag #bouncebounce to personalise their photos with Buster and the other animals. Visitors to John Lewis’s Oxford Street store will be able to try a virtual reality version of the trampoline, where they can bounce alongside the animals using Oculus Rift goggles.
