Unfairness to customer on purchase and promo

<p>I went to Makro Woodmead and bought a UHD TV on the 9th, 5 minutes before they were closing, the next day (Saturday) I went on their site and discovered that the same TV I bought a night before is put on special for a grand less. My issue is that I wasn't told/advised that there's going to be a promotion the next day of which I would have waited and actually bought the 55" UHD TV I wanted instead of the 49" and I would have saved a grand on the purchase. Makro is displaying a disappointing trend of not putting their customer first by advising on promos especially when I purchased a product that they then put on promo the very next day without first advising me or giving the product at the promo price seeing that I bought it 5 minutes before closing time.</p>
