"However, in 2007, helped by an internet campaign, the Wispa bar was relaunched, albeit for a "limited period.".[3]

Its trial run sold out in just under two months. It was announced in August 2008 that the bar will return on a permanent basis in October 2008. A bar will cost 45p. It was revealed that Wispa variants, such as Wispa Gold and Wispa Mint will also be reintroduced as "limited editions" alongside the regular Wispa's return in the Autumn of 2008."
