Not sure if it's relevant or not, but I thought I'd start a thread regarding suppliers running Black Friday sales:
CB Performance is offering 10% off orders $250 or more (excluding a lot of items) now through Sunday. The promo-code is THANKS.
AA Performance products has a sale running until midnight Sun/Mon. Prices are reduced on the site, with no need for a promo code.
CIP 1 is running a Black Friday/ Cyber Monday sale through midnight Mon/Tues. Shipping is free on orders over $99, and prices are reduced throughout the site.
Airkewld is running a 10% Black Friday discount now through 10/30/20. I believe this is site-wide. The code is Black20.
I'm sure there are more. If you have any information or codes, this would be a good place to share them.
