While the slavery-themed products are no longer available to buy on Amazon's British website, bags bearing the slogan were still on sale on the United States-based amazon.com this week.
The sale of such items by a major retailer trivialises the global drive to end modern slavery, said charities Anti-Slavery International (ASI) and International Justice Mission (IJM) UK.
"If it is meant to be funny, it fails miserably," Jakub Sobik of ASI told the Thomson Reuters Foundation.
More than 40 million people were living as modern slaves last year — either trapped in forced labour or forced marriages, according to the United Nations International Labour Organisation and human rights group Walk Free Foundation.
"Children the same age as those modelling the T-shirts will be forced to work long hours for no pay in desperate conditions where starvation, beatings and sleep deprivation are common," David Westlake, chief executive of IJM UK, said.
"Rather than trivialising slavery, companies and the global community must recognise the vast injustice of modern slavery and work together to end it for good," he added.
The imagery linked to slavery, and the issues it raises over history and identity, has stirred increasing debate with deep division over the fate of slavery-era statues in the US, and worldwide outrage about slogans and pictures used by big brands.
British supermarket Waitrose this month pulled a brand of coffee off its shelves after shoppers noticed the packaging featured images of 19th-century slaves working on plantations.
