To be honest, it's a bit of both
I used to post a bit more with deals etc, but it does feel like they're few and far between these days. Pre-covid and at the start of covid it felt like there was a lot more - e.g. the BWS clearance stuff, back when my wine guy was a thing etc.
Similarly, these days the ratio of deals/wine thoughts to cashback/etc posts has shifted quite a bit. Of course, today is proving that wrong (!) but in general over the last few months. I think redbigot did it well by separating the cashback posts into a separate thread on his forums
anyway, as you can see there's a lot of folks who like the cashback posts in this thread so i'm not going to lose any sleep over it, but i do wonder if there are others such as myself who have lost engagement a bit
