Ioffer.com is the biggest ecommerce scam right now in the internet world where they try to attract people towards products which are heavily discounted which is actually not.
When you make the payment of a product they will show you a price lets say eg.$52 but when you have just made the payment it will almost deducted the double or triple of it and since you have entered you credit or debit card, they will try to hack it. So be aware of this scam website.
