LPT: Do a reverse image search of items you see advertised online and pay less than half price.

I saw this sweater advertised on my news feed: http://ift.tt/2xXrJ9o After using the Aliexpress reverse image search, I found several sellers in China selling it for less than half. The reason for this is there are people who advertise the item online (despite not having the physical item in their possession) and sell it for more than double. They get your order then place an order through Aliexpress and put your address as the shipping address and keep the difference. It's called drop shipping and these people add no value to the purchase whatsoever. Don't get duped, do a reverse image search on Aliexpress.
