Do Christopher Ward promo codes ever stack with seasonal sales?

[Santimirova Sergij]

I'm in Austin and finally set aside money for a Christopher Ward, likely one of the C60 models, but the timing is tricky. I keep seeing promo codes mentioned for their site, and I've also noticed they run seasonal sales at certain points in the year. What I can't work out is whether those codes actually stack with sale pricing or if it's one or the other. My concern is waiting for a sale and then finding the code I have doesn't apply, or burning the code now and missing a bigger markdown later. I don't have any insider knowledge here, just what I've picked up reading around, and I'd rather not guess wrong on a purchase this size. For those who've bought during promo periods, how did it actually work for you? Did the code apply to already-discounted watches, and is there a usual window when these things line up? Any input from people who've navigated this would help me plan.
