There's no easy way to check which packs you have - all of them are listed under your NCSoft account as "Perk". You're going to have to go into the character creator, check what pieces are available, and then make a list of packs you have and save it somewhere so you don't forget it again.
Well, you don't have to look for *all* the pieces from a pack - if you have the Butler tux available, for example, you know you have the Wedding pack.
Character index
All of the costume packs have a few signature pieces you can use to identify them. Most of the newer boosters also have a power of some kind, or grant access to an exclusive emote.
And do note that this isn't a complete list of contents, just a selection of things that would be easy to look for from each set.
Wedding pack: /em confetti, the bridal veil in female hair, and the wedding tux which I think is under Jackets.
Cyborg pack: Self Destruct power and the combat auras. (The auras will be easy to spot, since characters will have them before level 30, no mission required.) You could also try the emote /em powerdown
Magic pack: for males, skull mask in face details and Baron Jacket under jackets. For females, any of the Witch outfit pieces, and Arcane Hood. Also /em juggle. The power is Mystic Fortune.
Natural pack: Ninja Run. Seriously, if you have Ninja Run, you have this set. You could also check to see if you have the Warrior or Terra options under Robes.
Science pack: Rubber gloves, or check to see if you can use /em calculate. There is no specific power in this set, but it unlocks the ability to change body size and even gender as part of a costume change with certain tailors.
Mutant pack: Look under Tails for Bioluminscent, or check the list of costume change emotes for one called Rapid Boil.
Mac Edition pack: Valkyrie Wings under back options, or Valkyrie Sword in the list of weapons for Broadsword and Dual Sword characters. The power in this pack is the Mission Transporter.
Going Rogue Complete Collection pack: The power is Shadowy Presence, and the easiest piece to check would probably be the Alpha and Omega auras. Again, these are available even to characters that haven't done the Aura unlock.
The Origins pack: Any of the included capes and Auras. Two easy ones to remember would be the Leaves cape and Leaves aura.
The Party Pack: I don't have this pack, but since it's basically *just* emotes, any of the ones listed in the description should work as a test.
*Edited to correct some of the pack names.*
Thanks for that list! That helped! A LOT!!!!

I sort of want a second account, but this has kept me wary, because it'd be so much work to go get them all.
There's actually a relatively easy way to tell which packs you have, up through at least the Mutant pack, if you're willing to use custom pop menus.
Edit: if you extract this into the data folder in the main directory for City of Heroes and then start up the client and type /popmenu packtest, it will bring up a menu that lists the CoH collectors edition, wedding, cyborg, magic, science, Martial arts , mutant and alpha omega packs (those are the only ones I have the Authbits for). Those that you have bought should show in blue while those you don't should be grey.
Edit2: Added party and GvE packs, and I have to say, if the quickmenu is any indication, we may have some interesting boosters coming.
Upon trying to purchase one of the packs, the store won't allow you to purchase if there isn't an account eligible for that particular pack. If you have one or more accounts eligible, you click a button to choose which to apply that booster to.
I am wanting to buy these various booster packs, the permanent ones, that I don't even have yet! The problem is, I do not remember which ones I have bought, and, which ones I have not bought, because the NCStore does NOT keep listed, ALL such packs that I have bought! It ONLY keeps a certain amount of them showing in the Transaction List! How can I find out which ones I still have yet to buy? Any constructive help, is, as always, greatly appreciated!
