Well, the simplest explanation for cheaper prices online is that you don't need a store front, only need warehouses and employees who manage those warehouses. All the costs for rent, fixtures, parking, maintenance, cleaning, etc., are gone. Selling online-only also means you get 100% of the advantage of bulk buying and selling- you don't need to "stock" product at locations, you only maintain a single list of "do I have it or not?"
RE: RightStuf, I've bought stuff from them before, their sales are pretty enticing, but Amazon's free shipping makes a pretty big difference as well. I definitely know when I bought FMP + Fumoffu BD, I compared prices and Amazon came out cheaper. No sales or Gold Box or anything, just regular price. Could just be that one occurrence, though.
