If your seller account is accepted onto Launchpad, an additional 5% fee will be added to the standard Amazon referral fees, for all the sales you make from your account.
There is a minimum contract of 12 months, and if your gross sales during that period exceed $1 million, Amazon might lower your additional fee from 5% to 3%.
After the initial 12 months has passed, you can cancel your subscription to the program by giving 30 days’ notice. But if Amazon decides that they no longer want you in the program, for any reason, they can throw you out before the 12 months is up.
