I have yet to buy anything for cash on Amazon. I have “bought” tons of free ones. I do plan on buying stuff for real money soon but I need a job first! I just HATE that I am not allowed to review ANYTHING even though they know I have gotten it from them because I haven’t bought anything. And its not even try want you to buy what you want to review. You just have to buy something.
If it bugs you that much, buy a $1 or $2 book. There’s a lot of them. Surely you can afford that amount of cash to change something that obviously is bugging you?
