If you like your lenses to ship with the fastest shipment option but at the same time you don't want to pay for fast shipping, Amazon is offering free 1-day shipping on various Nikon lenses. There is no page showing all the eligible lenses, so the easiest way to find out is to check each of the Nikon lenses you are interested in. The free 1-day promotion is mentioned under the "Special Offers" section, right below the product pictures on the individual lens pages.
This promotion is not just for the constant aperture f2.8 professional lenses, but it also covers some of the reasonably priced lenses like the 35mm f1.8 DX (free Tiffen, $200) and 50mm f1.8G ($220).
There is no coupon code to enter for the free 1-day shipping. Simply add to cart, select 1-day shipping and the shipping price will be adjusted at the top right corner of the Amazon Checkout page. You can always close the browser tab/window if you don't want to place an order. Please note this offer is only valid for items sold and shipped by Amazon itself, not by any of the many third-party sellers that also offer these lenses there.
This offer offers the biggest savings for non-Prime members, since you jump from Super Saver shipping to 1-day shipping for free. Prime members can also benefit, you jump from 2-day shipping to 1-day shipping for free.
