There are over 100 million Amazon Prime members around the world (more Prime members than non), and they typically spend over $1,000 a year. This might be an extra incentive to fulfil with Amazon, or at least make your items Prime-eligible.

For those without a Prime membership, they tend to spend a little less freely than their Prime counterparts. About three-quarters of non-Prime shoppers spend between $100 to $500 a year on Amazon.
