I just looked into selling on amazon...
while there are not crazy listing fees like on ebay, and you avoid paypal fees...their final value fees are nuts.
If I were to sell a redcat rampage for $700, amazon would get just over $100!
Ebay used to be about $50. I jsut checked tho, and that is going to be more like $75 soon.

These companies are not providing services worth what they think they are worth.

Must be nice to be the people who own these companies
