Tip for the purchase page:
Have it to where you can select the plan in a drop list or something, then make a price estimator on the bottom before the user buys it.
For the home page, don't just have a vertical list of plans, make it to where there are like three main plans in boxes, where they have their features listed below. Make the best / most bought one stand out. Pretty much like what you see on almost all websites that advertise their plans available for purchase.
