OK, time for another primer.
IFAK: Individual First Aid Kit, a small compact trauma-only kit. Designed to be used on you, the wearer, but protocols vary. Contents by definition follow the CoTCCC TCCC/MARCH guidelines.
GFAK: General First Aid Kit, a bigger, more comprehensive generalized kit, may or may not have trauma-specific items. Think under-the-sink kits at home.
Boo-boo kits: Mishmash of bandaids, moleskin, triple-A cream, etc.
You can purchase complete IFAKs from trusted Co TCCC/NTOA vendors (list later). Generally range in cost from $50 up to whatever you want to pay (>$200). The expense is often the bag/pouch itself (it should not be but some guys like Gucci), and the hemostatic dressing (hemcon, quik clot, etc.). The tourniquet is stable price across all kits around $25-$30/kit. For an IFAK to be a for-real IFAK, the contents must be 'certified', and 'certification' is a product of research and testing, not 'just' a stamp of approval. For example, there are a hundred TQs on the market, only a handful are Co TCCC approved. The pouch ir nag is irrelevant; a lot of people take the contents out and vacuum-seal it to save space.
You can buy the whole kit, or buy the bag of your preference and buy components separately. Perfectly OK. Me, I do both. Some guys build ARs, I like to build kits.
IFAKs are meant to be worn on battle belt or PC. You cannot use it if you do not have it. When I am shooting I have more than one kit, but the IFAK is on me.
IFAKs are not carry-in-the-car kits, they are not aid/RAID bags, they are not MCI bags.
Vendors include (not limited to): North American Rescue Products, Tactical Medical Solutions, Chinook Medical, Dark Angel (Gucci, you are paying for the name and bag). You really want a laugh? Check out Phokus Research. A million percent mark-up.
General First Aid Kits. These are what they imply. Not for penetrating trauma. I get these and add a TQ and a hemostatic dressing. It doesn't turn it into an IFAK or trauma-specific kit but it's insurance. You can get general first aid kits anywhere...Wal-Mart, Target, Dick's, Bass, Galls, etc. To me, there's only one and that's Adventure Medical Kits (AMK). I also use these for camping and hiking. For what it's worth, I do not take an IFAK when I go camping or hiking. I am not expecting a firefight. AMK can be found at REI or online.

Boo-boo kits. Just grab a handful of high-use things and find something in which to stuff them. Band-aids, triple antibiotic, some 2x2s and 4x4s and tape. I use a baggy and shove it in a GP pouch or in my range bag.
A list of Co TCCC-approved items is attached.
Seasonal stuff: In the winter I have a couple of those cheap mylar blankets, in the summer I keep extra water and rehydration powder on hand.
I have insider pricing with North American. If anyone sees a kit or supplies they like, let me know and I will see what my price is. I do not mind buying at that price as a service.
Ask me questions.
