Happies XXL in the U.S.

I have yet to try this diaper, but it's supposedly one of the largest baby diapers there is (>23 kg, which is >50 lbs!). I found a company in the U.S. Selling these diapers for $8.00 for a 20 count bag, and free shipping. The name of the company is ProductEarth.com. It almost sounds too good to be true. Maybe someone can shed some light on it? Are the Happies XXL diapers any good? Is the seller legit?
