A few T-shirt's at Jacamo have been reduced. They were on offer for 2 for £20
All the T-shirts that have been reduced to £7 or £7.50 work in the glitch.
The multibuy discount is still coming off the final price which is where the glitch is happening.
So add 2 tshirts to basket and use code HLCR8 and get 2 tshirts for £9 delivered
