Promotions that are not really promotions

I wanted to buy a baby Co sleeper for a friend. Went to Take a lot to check if they have it. Saw one that i liked and it was marked 46% off (R516). unfortunately i didn't have the money on that day. Now i have the money i went to Take a lot app to purchase the Co sleeper just to find that its now normal price . Which is ok. Guess what the normal price is R539. so now im wondering if the 46% off from R539 is R516 according to Take a lot. I have always been a loyal customer to them and i'm now wondering how many times did i fall for reduced pricing that is false.Ive been checking for the past 3 days thinking maybe they made a mistake but nah. Normal price is R539. Im honestly still in shock
