When she opened it, she knew why.
Sales says the neatly-folded diapers were filled with excrement and urine.
"I take the plastic bag out and immediately notice that it is heavier than normal," she said in a Facebook post.
"I place them on my bed next to my exposed child.
"I turn on the lights to my greatest shock.. these diapers are SOILED! It stinks of poop and urine! The packaging was tampered with and Amazon actually sold me neatly placed soiled diapers!"
Sales purchased the diapers from Amazon's "Warehouse" section, which offers opened and returned items at discounted rates.
An Amazon spokesperson told news station KYW-TV that the company is investigating the situation.
Sales was offered a refund on her Amazon gift card used in making the purchase, but feels the company was insensitive and failed to address the core issue.
"Amazon through their communication with us, telephonic or email, did not address the potential risk to the to the child's life," she said, "and that of the rest of the family, nor did Amazon suggest any potential remedial health screens that we should undertake to ensure that our health and our health & well being is not affected by this incident."
Sales said she did not accept the refund.
