Astronomical Sales by Mastercard, a unique sale – tied directly to an eclipse that hadn’t been seen in the region for 172 years. This made it an ideal opportunity to capitalize on what would essentially be Mastercard’s logo in the sky. When the eclipse started, so did the sale on the region’s biggest online retailer, noon.com. And as the sun diminished, so did the prices, reaching discounts of 97%, and returning gradually to full price. For those who purchased at the exact moment the eclipse formed the Mastercard logo, priceless prizes were awarded.
