Many items on Amazon come from third-party sellers on the Marketplace, indicated by a "Sold by" line near the "Add to Cart" button. If both Amazon and third-party sellers offer the item, the large "Add to Cart" button buys from Amazon, and you'll see a few alternative "Add to Cart" buttons with different prices and a link to a full list of used and new versions of the product. Marketplace sellers set their own prices, so you might find a great discount on a used item, or come across a rare, discontinued product that's only for sale at a collector's price. Even when buying from another seller, Amazon itself handles your payment, so you don't need to worry about your credit card information leaking out.
Amazon acquired Junglee in 1998, and the website Junglee.com was launched in India in February 2012 as a comparison-shopping website. It curated and enabled searching for a diverse variety of products such as clothing, electronics, toys, jewelry and video games, among others, across thousands of online and offline sellers. Millions of products are browse-able, whereby the client selects a price, and then they are directed to a seller. In November 2017, Amazon closed down Junglee.com and the former domain currently redirects to Amazon India.
Make sure there are enough funds in the account. Amazon tends to cancel orders until all funds can be paid out of your account. Contact Amazon for full details of what you can do to help them create the order, so you can get it to ship. Amazon doesn't take any money from you until the item ships. For those that are not "fulfillment by Amazon," you'll have to wait at least 30 minutes for the item to complete the transaction - These Marketplace sellers don't see any of your order until that window is clear.
