See even if the discount in offer is small, Ecom companies can call it a deal, whether it is a deal or not cannot be determined on the basis of amount of discount offered.
If someone has any issues with BBD or GIF they are free to buy it during regular days or anywhere else where they get the best deal.
No one is being forced to buy the so called "Deal" products only via the Ecom giants.
And considering the company aspect, they aren't here to do any kind of charity they are here to do business and businesses always want themselves be profitable.
Everyone is free to purchase the products from anywhere they wish no one is being forced.
Finally according to me even getting a discount of 1-2k extra during such sales is better than buying the products without that discount.
