Shipping containers went from USD 2,000.00 per container in January last year to USD 14,000.00 per container later in the year, and guess what the vast majority of shipping containers are made in China!
Felistowe has something like 16,000 containers and guess what even though the containers are electronically tagged and shipping progress an be tracj=ked whilst in transit, as soon as they arrive at destination they can and have got lost at the Port; so if there's a batch of Nippon Modus 105 Stiff shafts waiting for Mizuno HQ and they're in a container that has been lost.............THERE WILL BE DELAYS!!!
If you are missing an 8 iron waiting on repair, you'll have to manufacture a shot with a hooded 9 iron or soft 3/4 7 iron, teach yourself some new shots and be patient.
