Amazon Associates is an e-commerce affiliate.
It has over a billion product offerings.
Amazon closed my account and refused to pay for sales I made over 5 months. A week after I entered my payment details, they closed my account with zero warning and without paying. They have now ignored my email asking what' going on. They have ignored multiple emails at this stage. They also don't have a phone number so it's impossible to actually speak to a real person. Never trust a business that doesn't have a phone number. All legit, trustworthy businesses have phone support or an account manager you can contact.
You start your website, setup the links and everything, and after a while they close the account, don't tell you why, and you have no more access to anything. Since I'm in Europe I'll ask them all my data regarding my affiliate account, but I guess they'll never answer, because they don't care about you since the beginning.
And worst of all, they ask you to reapply.
