I am putting a couple of listings on Amazon at the buy box price level is 20% Roi too low? if I raise the price $1 it would give me a bigger Roi but would take longer to sell?
It's really only for you to answer. There are people that aren't happy unless they double their money and others are happy making a dollar. It's about what your time is worth, how much capital you have to invest and your tolerance for risk.
