I  ' knew a guy ' that was starting that kind of business ( delivery of items to homes after normal store hours ) and he ran in to a few issues.  The list I gave is a good one as he tryed to order ( against my advice ) for his ' regulars ' not knowing if they would suddenly stop ( which some did ) and ended up just barely breaking even after all the local taxes, paperwork in general, gas costs, etc.  The business was similar to ' dial a bottle ' but non-alcoholic items ie doritos, subs, pizzas.  If you just looked at the income, it was well over 1k ( canadian ) per month, but the taxes, expenses and buying ahead of orders that didn't come in killed his business.  Keep this kind of thing in mind and make it drive you FORWARD to make it a business you can pass on to your children at a point where they don't even have to lift a finger for it to have the coin roll in.
