@shabazmoqsud I didn’t get that email but I would assume there was something in terms and conditions along the lines of “whilst stock lasts”.
If there wasn’t then you are spot on. My last one had that in the terms of the deal for the Black Friday deals just gone. This isn’t something unusual. Every marketing/advertising establishment does that especially on deals. They can’t have stock available for every receipient of an email. One person may buy two or three or some may not buy at all. It’s just on how it is unfortunately. It’s always while stock lasts.
