A subscription service for diapers...?

Was thinking.. is it a good idea to start a subscription service for Diapers.. You know like a brand say Huggies could start an offer by which every week a set amount of Diapers will be delivered to the homes of subscribers.. What I am told is Diapers are a big expense.. and if the diaper people can give up some of their margins, they may be able to lock in assured demand from customers. The customers on their part will get a regular supply.. from what I know babies are slow at being potty trained. Chalo.. Am done for the day.. off to sleep! G'nite!
