Coupons for the whole range

Aliexpress decided to interest new customers with coupons:
4 $ from 6 $
5 $ from 7 $
5 $ from 9 $
7 $ from 9 $
8 $ from 10 $
9 $ from 11 $
12 $ from 14 $
14 $ from 16 $
UPD With coupons, some kind of ambush.
Not accepted by Aliexpress.
Symptom - either the system says that it’s busy or the order is immediately closed, while disappearing from the basket.
Options using new cards do not work
I tried the option with certificate payment, the certificate is bought, certificate payment also does not work.
4 $ from 6 $
5 $ from 7 $
5 $ from 9 $
7 $ from 9 $
8 $ from 10 $
9 $ from 11 $
12 $ from 14 $
14 $ from 16 $
There is a chance to get a coupon for an old account, but you need to check.
Another nuance ... Aliexpress does not miss payment from “illuminated” bank cards, so either start a new one or use, for example, a Yandex.Money virtual card
P.S. If there are not enough coupons today, there is an opportunity to return for them tomorrow at 10-00

Please clarify the knowledgeable comrades, what time they start to give coupons.
It used to be at 10-00 Moscow time, now in the comments they write about 11-00 Moscow time.
P.P.S Why do I remember about 10-00 ...
For example, in the rules of the game on Aliexpress
* In the application, you can play and win coupons from March 21, 10:00 to March 31, 9:59 2017 (GMT), and from March 28, 10:00 to March 31, 9:59 (GMT), the same game will be available on AliExpress website .
