いつもお世話になります。アマゾンで出品する時、相乗りできるかどうか判断コツがありますでしょうか？

ECマスターズの塚本です。＞アマゾンで出品する時、相乗りできるかどうか判断コツがありますでしょうか？ Amazonでは基本的にすでに登録されている商品に関しては、相乗りすることはどの商品でも可能です。ただ、一部のカテゴリに限り出品許可の申請が必要になりますので下記URLをご確認くださいませ。 https://sellercentral-japan.amazon.com/gp/help/help.html/?itemID=200333160&ref_=ag_200333160_a_r0_cont_sgsearch また、相乗りする商品でも既にAmazon.co.jpが出品している場合、価格競争になり、粗利を確保していくのも難しくなると思いますので、 Amazon.co.jpが出品していない商品を検討されるのも良いかと思います。

ご返答いただき、ありがとうございます。出品して、相乗りされない対策がありますでしょうか？

ECマスターズの塚本です。＞出品して、相乗りされない対策がありますでしょうか？例えば、セット組で商品を登録したりおまけ付きなどして商品登録をして、他社が相乗り出品販売できないような工夫をされている出品者は多いと思います。カートボックスの奪い合いにならないような商品登録を行うことも一つの手段になります。下記URLは参考になる過去の投稿になりますのでご参照くださいませ。 https://ec-masters.club/forum/post_view.php?id=384
