If you want bulk discounts on things you can be a GoDaddy Reseller. By being a reseller you can set your own prices for things and get them at 'cost'.
There are two kinds of reseller programs you can join:
Basic: 20% off everything ($108 per year) Pro: 40% off everything ($180 per year)
Both give you your own storefront to sell all GoDaddy products to your clients. A few things arent included like Office 365. You can set your own prices for everything and get cheap prices on hosting and domains.
