It's a bad example for sure, but COD CEs do go on sale. They get real cheap even, if you get lucky. COD CE's become uncommon, while this loot chest I'd describe as Rare, if not like Super Rare.
Examples from CAG:
So they do drop. But I couldn't find any price cuts that were like $99 or $79.99 or anything. So it's full price or hope you find a copy instore.
And I think his point was that they don't jump up in value like the B2 CE is doing and will most likely stay. At most they(COD CEs) stay at retail value, if not cheaper.
I just skimmed over that old thread I had posted about the Blops Prestige Edition. What a glorious day. Sadboy's "time to hoard this bad boy" post made me really laugh out loud just the way he was responding and all lol. Good times bud
