Disclaimer I don’t know anything about Strathberry themselves with this comment this is more general BF chatter - but there are CRM/email search engines you can play around with, you can also just use Twitter/Insta search to see what they posted last year.
IMO/ime Black Friday has been very same-y for the last 5+ years, brands don’t want to do crazy discounting as it isn’t in their best interests, plus trains customers to wait for discounts/cheapens things. Brands have been increasingly more interested in loyalty and/or incentivising higher order values so you (or any one looking to shop ahead of BF, anywhere) may miss out on something like points or a voucher scheme or buy more save more that launches on BF, but unless you’re buying a lot does that rly matter? Also you’re nearly mid month so could always buy & return under your old order id to recoup the difference. Funnily my husband wrote to a (sports shoe) brand as he’d bought some shoes and then they’d emailed him the BF preview, they just refunded the difference straight away
ETA - forgot the old gift with purchase - which will be overstock they want to get rid of so pls don’t let that influence you! Again who cares it’s shit they couldn’t shift the other 11 months of the year x
