New to Amazon FBM

You have to earn sales through the buy box. Even if you have the best price now you are a new seller with no track record. Amazon wants to see sales and shipping & delivery on time without a bunch of complaints against you first. You have to build a reputation. Everyone goes through this. All you can do is wait it out and hope you start getting sales here and there and eventually build up some metrics Amazon likes to see. Also, don't expect to get paid anytime soon after you make sales. Your funds as a new seller will probably be on hold for up to 30 days for your account level reserve. Keep that in mind so you don't freak out when money is not coming in. If you make more sales you can have more money held back in reserve too. New sellers just have to play the waiting game on here. Good luck!
