Alright. Gonna start posting up deals on files at times. They can be "bought" sometimes on backorder and occasionally get shipped. Most get cancelled or requested to get cancelled for a few months at times (last one in limbo for me is about 1 year limbo). You won't be charged until it ships, but it will still be an odd duck kinda thing that occasionally happens.
This is an example of one you could order, but it may be in limbo or just outright cancelled:

What you search for is packs. You order files via prime/amazon selling as you'll get the best result if they screw up (page and order for pack of 10, they sent one. Single box of 10, they sent single file). It means if you buy correctly though, you'll be getting these multi packs for the price of usually a single file.
3rd parties will almost always (not completely though) claim they're only selling a single file, so unless it's prime guarenteed, it's probably not worth it unless you're find sending it back (hence, prime for free returns).
Larger sizes tend to be in smaller packs due to size and weight. They tend to come in boxes with oil paper seperating each file. It's worth it if you are needing files, or have friends you can pawn them off on for the cost of a single anyways.
This is a prime example: $12.16 - Crescent Nicholson 08642N 10" Mill Single Cut ******* File - 12/Box
https://www.amazon.com/dp/B000W0ENAQ/?tag=atomicindus08-20
$30.09 - Crescent Nicholson 07719N 14" Flat Single Cut Long Angle Lathe ******* File - 6/Box
https://www.amazon.com/dp/B00018ABQ4/?tag=atomicindus08-20
$15.72 - Crescent Nicholson 07941N 12" Flat Magicut File - 6/Box
https://www.amazon.com/dp/B00018ABQO/?tag=atomicindus08-20
You can usually find one listing and browse related to skip past all the amazon search engine junk they spam in there. It's always hit or miss, and you may need to contact them if they shorted you, but it's well worth it for when you get them.
I only posted a few, bought a few as well. Sorry for the paper.
Reccomended for people who like to file on things for fun.[emoji38]_hitti
*EDIT*
Forgot to say, if you only need a few files, get a 6" Fine, 6" Coarse, 12" corse, 8" *******. That'll hold you over for the most part. The 12" will do most of the heavy work, the 6" corse is for smaller spaces, the bastards are great for middle weight, and the fine for the obvious.
