Yep. I remember 7 cents a round for that Czech stuff.
Personally I think I would purchase some of the polish ammo on stripper clips: I'm pretty sure that one can sell these clips. I remember buying those few I have at about 50 cents apiece.
At these prices one might be better served picking up a 8mm mauser over a mosin atm. Ammo is now roughly the same price and the mauser is a MUCH better rifle
I recently opened one of my last two tins of $0.08/ round hungarian FMJBT light ball. I bought a half dozen back in early 2007 when 7.62x54 really was a bargain.
