This is a must for any basketball fans out there and is almost half the price from any other other retailer.
Shopto are offering it for £21.15 including free same day dispatch for first class recorded delivery and if you go through quidco, you'll also receive 4% cashback too, making it just £20.30 all inclusive.
The next lowest price seems to be £39.85 but there's probably some vouchers to make it a bit more competitive but I doubt any enough to reduce the price by half.
Hope that helps. :)
