Rubbing salt in the wound

Man, I was so excited, we finally bought our brand spanking new Color Laser printer for almost R7000 yesterday evening, after eyeing it in my wishlist for a bit, but now we just have to wait for the delivery and we will enjoy it to its fullest. However, even though I added it to cart from my wishlist, it wasn't removed from my wishlist (but who cares right!). Well, this morning I got a notification from the Takealot app stating that the printer is now on special for R460 LESS than what I paid a few hours ago. Now, I fully understand that the price will fluctuate, I am fine with me paying R460 more because I bought yesterday in stead of today, but do you really have to rub salt in the wound by sending me a message basically saying: Hey, you supported us earlier so we just wanted to let you know if you waited a few hours you would have save R460. Really? I really only expect some sort of recognition that it was a bit of a d*** move to send me a notification, but I will now be a lot more weary of supporting Takealot before buying, well, anything really. Should we just wait for a sale and only buy then? I mean, my package have not even shipped yet but there you go, you wasted R460.
