Yes; having more than one account is a great way of keeping up with all of your amazon sites. I look at creating amazon accounts like how I create different adsense channels.
Creating multiple Amazon tracking IDs is more like Adsense channels. I'm not sure there's any advantage to creating multiple accounts over creating multiple tracking IDs...
Even we can have account more than one But it’s not to be good Thinking when we reached amount threshold let say 100$ in one account, but the other account still 15, and we need to get direct deposit, which the condition more than 10$ we can request for Direct deposit And what gonna be happen, in case Amazon paid 15$ via wire transfer or Direct deposit already, and the system understand it was duplicated transaction. I think one account is save and safe, Even for transfer money fee..^_^ This is my personal opinion only anyway
The only benefit I can think to having multiple accounts is if you create hundreds of astores, because there's a limit of how many astores per account, so if you want very many, hundreds, then multiple accounts will work. But if not, just create different tracking IDs in the same account.
Inside your initial account, you should be able to set that up. I have 4 in one at this point to track which one is earning over the others.
Normally , 1 account have 100 tracking id , if you need more than 100 tracking id you can send your request by email to amazon.
Why would anyone want more than 100 id's? It seems overkill to have so many. I have 4 different ones, to match whatever Niche I'm trying to use their services for, and could never imagine getting 100 or more tracking id's.
I found the same problem with you. limit of tracking ID, right? I have plan to open aStore ~400-500 store that mean I need to register ~4-5 account to support.
Another reason is Amazon may close your account for some random reason. If you have more, it reduce the lost.
