Still varies by location; everyone can check it out by using a private tab/window where they're not logged in (but you'll likely have problems changing the location and currency; they'll default you to roughly where you are based on your IP).
"Welcome deals" are sponsored by AliExpress, they pay the price difference, and you as a new buyer are limited to ONE item, with a quantity of 1, and that's so you don't abuse their system (too much) by opening numerous fake accounts.
I see it as 9,25€ with the regular price 9,72€, so not much of a discount. Other items may be at 50% or even 75%.
Recently I ordered two replacement garage door remotes, "welcome deal" had them at like 2€ + cheap shipping. After logging in, the price was 5,5€ per piece, free shipping if I got two or more. Messing around with two accounts and two orders wouldn't have given me much.
This reminds me - I still have to copy the original remote codes to the new ones, LOL.
