They like to ship things apart to reduce shipping fees for them i guess. what ever, we get free shipping. Also, they're quite busy right now due to chinese newyear just ending a few weeks ago. You can imagine all the orders that were placed during that period that had to get filled.
I personally have never had a problem with them, just takes anywhere from 1 week to 2 months for stuff to arrive.
They always seem to respond to my emails within a day, and happily give me the tracking numbers.
