I ordered two Sanyo 18650s 2600mAh (the red ones) from Kaidomain. They were posted on the 4th of May and arrived this morning! 5 days to the UK and only regular airmail. The quickest record was Solarforce at 7 days but that was 'signed for'.
This is not flashlight related but at my business we are able to order small tools and cleaning chemicals as late as 4PM and get them the next day from various suppliers that within 150-200 miles away
In all fairness, On the very same day I received an order from Dino which took only 12 days. Things are looking good since China got jet engines. Before, stuff came on this!
