I ordered mostly AliEx choice items during the 11.11 sale and the bulk of the items arrived within 5-7 days. In fact the only item that hasn't arrived yet was something I ordered back on Nov. 3rd. My recent orders have been arriving via a nondescript courier (doesn't say who in tracking), sometimes just delivered by a private car. Interestingly enough, even more bike frame brands are starting to store their frames in US warehouses. I think AliExpress is following the Amazon warehouse model.
Though Amazon still has some hidden deals. I recently found a 2x MTB direct mount chainring for $6 USD on Amazon Prime. Same chainring goes for $16-20 on AliExpress. Also I like to search the bargain bin aka Amazon warehouse section for return items. I've found unused Panaracer GravelKings and Conti GP5000 tires for half off retail that way.
