here some tips from fb

Just to clarify some confusion here. Many people complaint that item sold out within mins.

The truth is you secure your item once you already filled up the details and click check out. It doesn't matter when you pay as long as payment is completed within 24 hours.

Here are few tips how to secure a unit for yourself.

First, login 30 mins before 12:00 to avoid server overloaded. If you login around 11:50, you might just stuck there.

Second, type your shipping address in advanced. Later just copy and paste to save up time.

Third, by 11:58 keep refreshing the item you want. After click buy, quickly fill up the details. Paste the shipping address that you have copied and press check out. Once you press check out, the item is yours.

P/S: Double check my order section if you have check out, but the cart is empty.
