All KEF products will be subject to "significant discounts" in store, including the range-topping Reference Series and new Q and T Series speakers.
Although Unilet doesn't have the entire KEF range in stock, the sale prices will be extended to include any KEF products ordered at the weekend.
Customers simply have to order them and pay a deposit on the day to secure them at the sale price.
In addition to the KEF discounts, Unilet is also offering a further 10% discount on all remaining stock in its Blue Murder sale.
