You'll have an easier time negotiating "extras" (ie: granite, stainless steel, hardwood flooring, upgrade appliances, whirlpool tub) than price, because the developer doesn't want your "discount" to show up on the sale price. If others who've purchased for full price, in your development, catch wind of your discount, they might be a little irked, and the reduction of your price is public records, but the free, or discounted upgrades do not show on public record.
Always consider how many units have sold (as a %) and what discounts or free upgrades those buyers got.
Adding on to Elvis's answer below, don't be afraid to ask for a free parking space, a credit toward closing costs (if allowed by your lender), or interest rate buydown. Good luck - its a great time to be a buyer!!
