I prefer Amazon over others with comparable or lower prices due to their return policy. For example, newegg return policy are harsher to the customer than amazon.
How are the return policies?
I have an amazon prime card that gets me 5% cash back on all purchases on amazon. I competing service must therefore be at least 5% lower.
I would love to ditch Prime. I pay over a $100 for it every year :-( But I have hand no hassle so far.
