It sure is basic maths!
Looking from the consumers point of view, ......two ARB lockers from the States - AU$1800 to my door, whereas travelling 20 mins to my local ARB store to pickup the same product will cost me AU$2500!
...and as a consumer wanting to buy NOW, who cares what happens to the locker prices in future, only the current pricing matters!
I admit that warranty may be an issue, but that's effectively a AU$700 insurance policy (39% premium!), which may be worth it for competition users who are stressing the parts to the max, but for the average user (like me :p), it's very hard to justify.
