Its not working because "Retro Shop" is not offering any promo codes or sales for Black Friday/Cyber Monday. The promo code you mentioned, TRSGIVING25 is for "The Retrofit Source", which is a completely different site, and different company, than the Retro Shop.
Either you just mislabeled TRS or your confusing the 2 sites. Either way, Retroshop never does any sales.... ever. The Retrofit Source on the other hand, clearly states in every ad and email about their Black Friday/Cyber Monday sales that the 10%, 15%, 20% and 25% off promo-codes will not work on ANY Pre-Order items.
Sucks because with their BF/CM offer of the free XB LED Fog Lights if you buy the XB LED Headlights, if you were able to use the 25% off towards the headlights, you could basically get the XB Tail Lights for free with the money you'd end up saving from the $ off the headlights and the fogs being free, so buying all 3 would end up coming out to basically getting the XB Tails for free which would be a sick deal. Or you'd get the XB Headlights + Fogs for around $1,012.50 and that would just be a ridiculous steal of $1,550 worth of parts, saving $537.50 lol.
