For those who buy from China via Amazon, BangGood, AliExpress, et al, remember that Chinese New Year is just over a week away: the holiday runs from January 27th - February 12th.
During those days, the China post office and shipping agents will not work, so orders won’t process and packages won’t ship.
If you are looking for cheap electronics, etc. you might want to hustle up and get your orders in so the parts can ship and leave the country before the 27th.
