Thorfire sells on amazon, and their discount codes are set up to work there. I like that! The benefits are fast shipping (days not weeks) and easy returns.
For example this light: https://www.amazon.com/gp/product/B0787Z97ZK/ref=ox_sc_act_title_1?smid=A2R9O9RPRP4XXU&psc=1
Use this code: 3VSIRROL to lower the price to $23.04 (it’s working today I just tried it)
Review here: Thorfire TK 18 / Full Reveiw..20% off code just added
Thorfire sells the BLF Q8 on amazon and there’s a code that can be found for a good price.
.
Another brand selling on amazon is Sofirn, they have many great lights, codes in this thread: Special code for BLF from Sofirn. New arrivals— C8A 2 light group and max up to 1747 lumens.
.
I buy a lot of flashlights using the codes found on BLF for Gearbest and Banggood, sometimes the code is expired and then I keep looking elsewhere and find one that works or wait till a new code comes up again.
Here’s a few tips:
- If you try a code and it doesn’t work send a PM to the member who supplied the code, they will help.
- As suggested look for the “Flash Sales” on Gearbest and Banggood, those run often and no code is needed.
- Also as suggested, register at member M4D M4X deals page: https://m4dm4x.com/m4d-m4x-deals/ Martin has many deals and they’re well organized on the site ….(If you ever have a problem with his codes not working send him an email and he will help)
Some other members also have external deals sites that are also good.
- Follow this page to find deal threads: http://budgetlightforum.com/forum/marketplace/commercial/liaisons
- If there’s no working code don’t forget there are “General codes” for BLF members that work all the time:
Banggood : 4BLF for a 9% discount (flashlights and batteries)
Gearbest: GB17LED for a 12% discount (flashlights and LED lighting)
Fasttech: BLF for 5% discount (flashlights and flashlight parts)

I also buy lights on Aliexpress, no codes needed, prices are already low and they run sales a lot:
https://www.aliexpress.com/wholesale LED+flashlight
Sofirn lights are also on aliexpress for great prices - no code needed - prices are about the same as buying on amazon with the codes:
https://sofirn.aliexpress.com/store/2933049?spm=2114.10010108.0.0.679aed19rnxlOv
.
Another good source for popular lights is Convoy store on aliexpress: https://convoy.aliexpress.com/store/330416?spm=2114.12010108.0.0.68d35d27MiCJEO
The owner (Simon) offers a 15% discount for BLF members, no code needed, just place the items to the cart then send him a message through the Aliexpress message system and ask to get the BLF discount, then wait till he adjusts the price before you checkout.
.
I’m not affiliated with any of the sellers/online stores I listed and none of the links I posted are affiliate links. Just did this to help the OP and new BLF members.

Some suggestions for the $300 spree: 
- Thorfire TK18 from amazon (w/code)
- Thorfire BLF Q8 from Amazon (w/code)
- Sofirn C8F and C8A or C8T (also many others) from Amazon (w/code)
- Convoy S2+, L6 (also many others) (with codes or member discount)
- Thrunite TC20 (with code TC20) (currently under restocking, worth the wait)
TC20 3800 Lumens Floody Flashlight
Thrunite TC20 - XHP70 - 3800lm
Hope this helps, good luck and have fun!
