Price irregularities!

I am now convinced that Takealot is inflating prices, i put a pack of ink cartridges in my wishlist on Takealot last week Monday and they were priced around R139 if I’m not mistaken. I go to my wishlist with the intention of checking out, and to my surprise the ink is nou R349.... supposedly on sale from R699. That is very surprising how the ink less than R200 a week ago to now 3X the price! You must take us for fools
