Chinese Component Sources
Banggood.com some of the guys like it best, (prices may not be the best)
AliExpress.com Retail oriented offshoot of Alibaba (use it for a few months, it's been OK)
Ebay.com There are electronics specialty stores with lots of components, in some cases it pays to buy multiple items from some sellers, some will ship your entire order up to 1 Kilo for a flat price under $3. I was fed with Ebay after mis-representations on ads at what turned out to be general merchant sites, better to stick to component specialists.
For the adventurous buyer, there is the TaoBao domestic Chinese marketplace, which apparantly has the best prices, apparently checkouts are not automated, you must "chat" with the seller, the article below recommends hiring a purchasing agent to assist with your order.

Source Parts on TaoBao: An Insider’s Guide by: Naomi Wu
The Shenzhen resident gives tips to the brave for faking your way through Chinese language sites, like TaoBao, which is apparently much larger than AliExpress.
They apparently don't ave automated payment/checkout, you have to "Chat" with the seller to complete the transaction, you can employ a Chinese middleman and still save lots of money.
For obscure, small production run electronic assemblies, try Tindie in some cases, it may be the first place to find some new technology innovation. (Shipping charges can be a deal breaker with some sellers)
Adafruit is a strong contributor to the community with tutorials, and providing open source drivers that are the standard in many cases. Price + shipping is high (factory in Soho NY) they are well represented by Microcenter (Tustin) and several online sellers. Help support them when you can.
Sparkfun is another US seller, that also does some education, they appear to sell Chinese made boards as well as their own designs. They just ended their Autonomous Vehicle Competitions after 10 years, says most of the challenges have been solved.
Arrow.com often offering free overnight shipping, their store database is not very sophisticated, they handle some products by Adafruit and Seedstudio, etc. with quicker shipping and lower sale+sip cost in many cases.
Seeedstudio offers lots of new products of their own design and from other manufacturers, they also provide board manufacturing service and component kitting.
New product announcements and reviews
Lots of new Embedded Device product news
https://www.cnx-software.com/
mbed.com the iot oriented site by the ARM computer designers, as lots of data on Boards, Modules and Components, as well as drivers, example code and an online compiler. Scroll down to Supported Hardware.
MickMake gets bags of component samples that he reviews on youtube.
