What you have to remember with Canadaammo is when they bring something in, they get it probably a year after they actually ordered it! Direct from the manufacturer or the likes and in bulk gets YOU a GREAT DEAL but for a limited time.
*if* they ever get more SKS's, they will be a great deal, but it will probably be a year before they get more (if they ever get more military Chinese SKS's). Look at the Grizzly shotguns, its usually a year or two prior to them getting the Grizzlys that they mention what they might be bringing in. Hence why their 12.5" mag feds had sold out in about a week, because it had been over a year since they last had them.
They brought in the norinco 213 (chinese copy of the tokarev) for $99 3 years ago or so. I have never seen a new pistol at that price, EVER!!!!!!!!!!!!!! But, its a one time deal. Even today I still hear people talking "man I wish I bought a m213 when canam had them for $99 wow I was an idiot"
Norinco M93's were selling elsewhere for around $180-$200, then you had to spend an extra $30 to $40 for an extra magazine (even though inside the box you could see the spot where the extra mag was shipped from the manufacture, until other retailers took it out and sold it to you for more separately), plus shipping costs.
When Canadaammo got its hands on the norinco M93's they sold them for $150(best price out there!!!!! With 2 mags!!!!! FREE SHIPPING!!!!!
I bought mine elsewhere a year before and paid about $250 for the exact same thing (pistol, 2 mags, shipped). But canam will probably never get anymore, and if they do it will be a year from now or more. Snooze and you loose.
So in short, if your cousin wants a case of ammo, buy 3 of them. Cause its going to be gone soon, might never come back, and you wont find this good of a deal elsewhere. Store the extra cases under the bed, or in the basement, or in the attic, or under floor boards if you must.
My 2 cents.
