the long and short of it is that they sell LOTS of items to almost all countries in the world.
Every club you go to in every country will have zippy lipos.. quanum battery watchers.. etc etc.. I dont expect a 24hr service..

Their workload must be MASSIVE... what with all the sales... then packaging... ticketing ... restocking... loading unloading trucks non stop etc etc

You just need to buy without any rush or anticipate the wait..
