Another very common mistake and trun off!
For similar products, you often see offer which are radically different in pricing.
If you offer the same as your competitors for a price which is 5 times higher, you better have a way to justify that!
There must be something, some features and really good reasons to have that price.
You can't just be blind and pretend that these competitors don't exist!
Listen to the market you are in a price accordingly!
