Destiny 2: Lightfall $61.46
Not sure how this deal will be perceived, a lot of money for a DLC pack that isn't out yet, but there's going to be quite a lot of content. Good deal if you're going to be buying it anyway.
So what you get now (aka the pre-order bonus) is the Quicksilver Storm Exotic weapon, a new Exotic Ghost, Exotic emote, and Legendary emblem.
What you get later is the Lightfall DLC, the new raid (launching tomorrow), two dungeons released in Season 21 and 23, a new Exotic Sparrow, the Quicksilver Storm catalyst and ornament, and Season Passes for Season 20, 21, 22, 23. Plus 4 "Rahool’s Secret Stash" deliveries (once per Season) that each contains 1 cosmetic accessory, 2 Ascendant Alloys, 3 Ascendant Shards, 1 Exotic Cipher, and 5 Upgrade Modules.
If you're not wanting the Annual Pass, they also have a discount on the Lightfall DLC on it's own.
With the DLC on it's own, what you get now is a new Exotic Ghost and Legendary emblem, then later on you get the Lightfall DLC, the new raid, and a Season Pass for Season 20.
I've always pre-ordered through GMG, and in the past it's become cheaper towards the release.
So it might be worth waiting if you're not fussed about getting the pre-order rewards (and exotic gun) immediately!
