I will come off as bitter in this post but it is my personal opinion that it's kinda *&%&ed up. If you got something for free, it has to affect the way you review a product. You (the person receiving something for free) bypassed the part where you had to work for the money to pay for said product. It just always seem to me in almost any situation that people who began something from an early point of a predicated boom (i.e. the boom in nail polish blogs) are usually the ones who get the most recognition and in turn, more demand for advertisement by nail polish companies.
I sometimes wonder what position I would be in if I were sent something for free and I genuinely liked it but never got to experience what it's like to work to be able to buy something. However, I have never had an opportunity where I would receive something for free so I don't have an experience with that. It definately can't be the same as receiving polish as a gift from a friend. But if I had that experience, how would I handle it? I think I would ask myself: Would I have bought this using my own money because I genuinely like this colour? and go from there.
Usually I wouldn't even care if you got it for free but it's been bothering me with the FTC rule changes that surfaced recently. Could you maybe share some insights and rebuttals? What is your opinion on free press samples? I'm sure you all are familiar with them.
TL;DR: consumerism sux
