I saw a post about Gumroad on Pixiq, and its premise piqued my interest, as it may do for my readers.
Gumroad claims that it serves to democratize the ability to sell stuff online, and 'stuff' obviously includes photographs, or songs, albums, videos, and other products. It does so by creating a link to your photograph(s) so that your fans, friends, and followers who want to buy it, can do so, and no store set up is needed.
Gumroad's fee structure is states as 5% + 25¢ of each transaction. If you sell a photograph for $100, the fee is $5.24 and $94.75 is deposited into your bank account. According the Gumroad's FAQ, it supports Visa, MasterCard, American Express, Discover, JCB, and Diners Club cards.
It may be worth one's time to try this service out.
