You can get anything on Ebay

I spotted the following advert the other day.

Example Advert


Although I could not actually find anybody selling human fleas on Ebay, there is something in their terms and conditions that would let you sell them. It's possible to sell "hatching eggs" on ebay provided you only offer domestic postage. Your only problem then would be to find someone who is willing to transport them, I'd expect that having the fleas hatch out in transit would lead to disaster. Perhaps best to ask people to collect.
