Do not buy anything from firstcry.com as their sales are just fraud and conducted to increase in their traffic from which they can earn more and more revenue.
Whenever they conducts any sale be sure to install buyhatke extension in your browser to see the price increased by them because every time there is hike in prices slowly or one time big hike and then they give us discount on that item even if the price after discount is much more than the original price.
I have personally experience it as I was making some shopping for my uncles son and tried it as I have buyhatke extension installed previously I got to know what they mean by sale or I should say by the sale is a loot to them as they only loots the customers.
Also they conducts 100% cashback sales that goes out of stock in 3-7 seconds how it could be possible. It is possible because they do it on their own profit and they get high traffic due to that shitty 100% cashback sale. Till now I have tried 12-13 times with a internet of 3mbps and I was not able to put a thing in cart as my page loads I put in cart address is pre-existing but it goes out of stock.
I will sugges you not to waste your time, money and internet on this fake site and try any other site or local market.
