Youngster William Bateman won the specialist truck in an eBay auction after his mother, Fleur, left her computer logged in to the site.
Distraught Fleur immediately contacted the website in an attempt to retract her son's winning £3,500 bid.
The mum of three said "I had to beg them to retract my bid when I was congratulated on my win on the site. I can laugh about it now but at the time I was so shocked and angry."
The dustcart would have joined William's extensive collection of refuse collection memorabilia, which includes toy wheelie bins and miniature lorries.
The boy's love for rubbish began when he was a baby and he now dreams of becoming a recycling plant manager.
He eagerly awaits the weekly bin collection at his home in Great Paxton, Cambridgeshire, to see the bin men in action.
The schoolboy even lectures his parents' friends on recycling and tells them off if they do it incorrectly.
He said: "I think it's really important to recycle and put rubbish in the bin. I love all my bins and I know lots about it."
His mother says that she and her husband Paul spent months searching for a children's book about a binman, as William refused to read about anything else.
Consequently, Fleur took it upon herself to write 'Burt the Binman' which is due to go on sale in W H Smith
