Aliexpress will do any other marketplace at prices for Arduino. You can still pick at Banggood, but Ali will be more abruptly. Option still DX. But some positions are the same Uno boards, still better on Ali. But in general, this process can be performed in a circle in all these three sites.
P.S.
I sketched a list of Chinese sites where I saw boards and personal belongings for the Arduino:
Aliexpress.com
Banggood.com
Focalprice.com
Dx.com
Gearbest.com
Lightinthebox.com
Tomtop.com
Sunsky-online.com
Focalprice.com
Elecrow.com (by the way, a very curious resource. I recently found it)
Jd.ru - traces of Arduino presence found
Other interesting shops:
adafruit.com Another interesting store. Perhaps not the cheapest, but there is a choice there and many refer to it.
shop.pimoroni.com
sparkfun.com
electrodragon.com - it seems not expensive.
www.mantech.co.za - I did not really have time to learn whether it is possible to buy something there at all. But almost every position has a datasheet, which is also interesting.
It makes sense to check at all, something somewhere is always cheaper, for example, you can run into discounts. I just made an order the other day and ordered everything from Aliexpress.
There really are nuances. If you order everything from a single seller, it will be 1 order and you can easily make a more or less quick delivery with a tracking code.
But the small parts purchased in different stores on Ali, will go by different orders and most likely without a track, because you need to pay extra for it separately.
At the same time on other sites conditions may be different. But again, a penny detail is also likely to be sent without a track, although there may be exceptions.
In addition, when choosing a site, if the price is about the same, then you can choose the cashback with which is higher. Though I took on Ali, but with Banggud I could return twice as much.
So, you know, you have to be careful.
I will replenish the list if you want. It already seems to me that a vision emerges, who on Ali is less or less better or worse.
