Some good prices for this seasons kit on Kitbag made even better by the 20% off - deliver is £3.95 but remember you can also earn quidco cashback.
The Arsenal international away top is £11.99
Barcelona home top is £15.99
I even noticed if you order the Barcelona home top that you can add 'Hero' printing without increasing the price - £15.99 plus delivery to have Messi 19 or similar on the back. Now that is a bargain even if it is an out of date kit.
