I used to buy the Remington Golden Boy 525 round box at my local hardware store for $6.99 but I can't get it anymore because that store closed.
So as the last panic when the .22s price went through the roof I bought up a bunch of rounds that no one wanted the price of these was at the time less than the .22s per round. I bought most of this 5.45x39 ammo for less than $0.09 cents per round.
Each spam can has 1080 rounds in it & each case has two spam cans, so that's 17,280 rounds not including the 750 rounds in the cardboard box on top.
Total cost I paid was about $1555.20 what the stack is worth at todays prices, $17,280.00 or more since these can not be imported anymore, probably worth more.
