Fortunately, we don't do coupons. Interestingly I've had a few nutjobs over the years that have emailed me with:
"XYZ is doing that for {amount} cheaper!" Why would you even do that? Is that like some ego trip thing? "Ha! Look how clever I am. I found it cheaper elsewhere!" So go and buy it there from there then. Sheesh.
I await some silly sausage to come back with: "Perhaps they were doing you a favour and telling you to drop your price a bit." 🤦♂️
