I posted the deal, but it was not showed up, and i can't search it.

I saw the direction for Amazon sellers before, in the forum, and you can check the pinned posts.

You need to indicate you are an Amazon seller in your profile. You can search Amazon, or click the hashtags you post to find if your posts pass. Hope my answer is useful~

AngelaGoodluck, you can see any deals you have posted from the Deals link on your profile at https://www.dealsplus.com/user/AngelaGoodluck/likes?selection=posted. While your comments on deals are shown, there are no deals for the categories posted, updated, or upvoted. You may not have completed the submission process, because all your deals would appear on that page.

AngelaGoodluck,

A lot of your deals are buried because they are not meeting the min. requirements: https://www.dealsplus.com/answer/new_direction_for_amazon_seller_7_26_18/29966

And just in case, creating a duplicate account is strictly prohibited.
