This document discusses a case regarding a promotional offer by Marks & Spencer (M&S) where customers could purchase three food items for £10 and receive a free bottle of wine. HMRC considered that the deal was actually for four items for £10 and that VAT should be paid on the portion of the £10 attributable to the wine. The First-tier Tax Tribunal agreed with HMRC's view, finding that the economic reality was a package deal rather than items plus a free gift. It determined that the £10 payment should be apportioned with VAT paid on the wine portion. The Tribunal emphasized examining the commercial substance of promotions for accurate VAT determination.
