Think that deserves a thread of its own.
and that is why the kit will sell! Matchdays Kids will be begging parents to buy them a shirt, any one off visitors to the store will be buying one too.
The Colour of the whites isn't an issue, in regards to Amex white and Normal white.
However the T-shirt material and the white transfer will always be different as the two materials are different.
I'd expect they have used the same pantone for both, however the transfer has made it look shiney...
