I have been using multiple methods on Alibaba to entice electronics sellers into sending me free stuff.
I have had success with big ticket items already.
I initially failed with it by using the "I am a college student majoring in (English related topics)" with many variations. This gave no success.
I then decided to use a simple method to try and get some big items.
I have currently got a 4K TV, a 62 inch 1080p TV, several phones, several TV boxes, several tablets as well as an official iMac Pro 27 inch.
This is how I did it.
