An item I bought from Boots has been reduced significantly... can I return it for a refund then buy it again at the lower price?

Hubby bought me a fragrance set for £99 in Boots, it is now reduced by £34. I have not opened it. Can we return it for full refund with the receipt and then just buy it at the lower price..... in the same transaction even? Or does anyone at Boots see the sense and can just refund the price difference? Thoughts on this thanks!
