S.T.A.R.T.
Overview
The P2W Vendor (or Transact 4 Victory in Praetoria) sells, for in-game currency, everything which players could spend real money on before the 2012 shutdown. It also offers access to some additional functionality. P2W Vendors are located in the tutorials, in the starting zones (Atlas Park, Mercy Island, and Nova Praetoria), Pocket D, Fort Trident, The Crucible, and Echo Plaza (event co-op zone in the Shadow Shard). The jetpack vendors were replaced with P2W vendors in Grandville and Firebase Zulu. Lastly, during the Winter Event, a P2W vendor is located in the Winter Forest.
The P2W Vendor in Pocket D, Echo Plaza, Fort Trident, and The Cruicible are accessible by characters on a Task Force or AE Mission.
Custom XP Rates
If you are not level 50, you can select a custom XP rate. This reduces inf gain by a like amount and lasts for eight hours or until cancelled in the Powers window.

These 5 enhancements are free, but unique. Until level 21, these are some of the best enhancements you can use.

You can also choose from a selection of melee and ranged prestige attacks. These are free if you have fewer than three total.

Recipe & Inspiration Drops
For a small fee, you can no longer get drops of various categories of IO recipe - Common, Uncommon, Rare, or Very Rare and PVP. You can also re-enable these drops.
For small inf fees, you can disable inspiration drops by type (eg accuracy, damage, endurance) or size, or re-enable ones you have disabled. You can also enable dual and team inspirations.
It is important to note that disabling IO or Inspiration Reward drops does not 'cycle' to a lesser reward, or pick a different option behind the scenes. If a recipe drop would have given you a disabled recipe type, instead you get nothing.
Using the Inner Inspiration prestige power would grant fewer inspirations with disabled inspirations chosen, issuing nothing in place of the rejected inspiration types. It is possible to activate the power and receive nothing if enough inspirations are disabled.
Revoke
You can remove various P2W powers if you no longer require them. This is useful for swapping Origin Powers, or for those classes of power where one is free but a second one is expensive.
This only removes the power. It does NOT give a refund.
Temporary Powers
A variety of temporary attacks. Most of these are useful only for character concept, but the Envenomed Dagger power heavily debuffs regeneration so is useful for Archvillain and Giant Monster fights.
