Bummer about the voucher, but I do understand why, considering basic core items are never in stock.
What was being referenced as the “flash sale” in the email? Was this the sale we’d sometimes see towards the end of summer on some items (I think it was 10%?). I don't remember much beyond that.
I agree with Giles, the items for elite members would leave a sour taste in my mouth. I spent a fortune in 22, 23, 24 but not nearly as much in 25. If it was calculated by last year I’d look like an infrequent shopper and not “loyal”.
Personally, small, quality items included in a purchase as a nice surprise would be fine with me. Mugs, patches and smaller quality items that probably have high margin and low cost for the brand would be nice thank you’s.
