2 t shirts for £26!!
Buy any 2 t shirts from my range for £26. That is a saving of £3 if you bought the t shirts separately, or you can look at it is getting the second one for £13. Either way it is a bargain!
Rather than listing each design separately which would complicate matters, simply click "Add to Cart" add to and proceed to the "Checkout". At the "Checkout" stage you can then simply list the esign, clour an size of t shirts that you require.
