I requested a code on Saturday October 5th in post #190. This was 5 days before the sale ended. I just received my discount code via PM so I used it when I placed my order for one flashlight (and two unrelated items) at amazon.com.
The Sofirn light won’t be in stock until October 31. Apparently Amazon will ship all three items together when the flashlight is in stock again. This explains the estimated delivery date of November 7th for my entire order.
I am happy! 
I can see I am late to this party, but I respectfully request a discount code. Thank you Sofirn!
I know that this is a long shot, but I would love a code if there are any left! Thank you Sofirn for your generosity!
I got a code for my post #11 on October 22! Sadly I’m not able to order from Amazon US as I’d written in my post. I explained it to Sofirn, but without response. I won’t forward to code, so please don’t PM me. 
Interested
I received my light today - it’s charging.
Ordered, thank you Sofirn
Code received today, light ordered. Thank you
Light ordered. Thank you Sofirn. 
Received my SC31B today. As others have stated, this is a very nice light that is well worth the normal cost.
I asked for a code days ago with no reply, can someone pm me the code please? 
received mine. great light. not sure how long they will keep sending codes out. it’s very generous. Thank you Sofirn!
I am interested! (if the codes are still available.
I’ll take a code if available!
Thanks!
I would like to receive a code, too. Thank you.
I believe they are giving 10 per day and started at the top of the list. My post was in the 100’s I don’t know how far they will make it. good luck though.
That’s how it works, Thank you. I will be patient and wait, sounds like a great deal. Thank you
Any more Aliexpress codes?
Just got a code and ordered. I can’t believe sofirn is still going with these! I’m so glad I was wrong on my earlier posts. Thanks you Sofirn!
Light received. Thanks!
