Pre-made packs upcharge and you end up spending more per item>Paying more for convenience factor>Paying for the useless items they throw in to drive up price>Only get limited amount of useful supplies
Maybe you can't buy individual band aids, but you spend $2 on a box you'll actually use for a cost per item that's lower. Plus you have plenty of spares left over for when you need to refill your kit.
Companies like NAR make good products, but compare the price of one of their pre-built IFAKs to what you can get by purchasing items individually from grocery stores. There are some things I don't cheap out on (like tourniquets), but gauze is gauze and band aids are band aids.
Again nothing I'm saying is a guarantee because prices can vary wildly based on companies, resources, your needs, etc, but a tailored first aid kit is the way to go no matter what; the cost benefit is just one of the factors.
