grabshoppingdeals.com is a fraud website.
Modus operandi: They call you to sell their products. You will receive an order confirmation on email. That is all the communication you will receive from them. No matter what you buy, they will ship you a cheap watch. When you call their call center, they will say it is a promotional gift and the main product will be shipped shortly. After a few days, their phone will be switched off. Scam over.
