I ordered from AliExpress in early Aug. Items have still not arrived but its OK as I don't have any urgent use case for them. Default shipping is typically SG Post or AliExpress. The former method in the past never arrived and had to get a refund which was easily granted by the sellers. The delay seemed to be virus related. AliExpress is reliable but slow. I beleive its ground shipment within the Mainland into HK. On a prior order, most items took about 1.5 months. One order (for what I determined to be fake but non critical auto parts) arrived from a closer province whithin a few weeks. If you can, as its not always disclosed, determine where the items will be shipped from and the closer the better IMO. If you are going to pay for expedited shipping its better to consider eBay or Amazon IMO.
