I would pay the cashier $1.25 for a box of .22LR, a pack of unfiltered Camel cigarettes (with 2 new pennies inside the celophane), a Coke and a few candy bars.
I would then load my rifle, light up and pedal off to go rabbit hunting.
Any kid doing that today would attract a SWAT team, and the drugstore clerk would be jailed.
I remember when my buddy and I would kill a large Coon, we would take it to the Black section and sell it for 75 cents which was a pretty good bit back then.
We would then go to the store and buy a box of cartridges. They were .75 for long rifle, .65 for longs and .55 for shorts.
I think today due to mass production, .22's are far cheaper when inflation is factored in. In fact one can still buy LR for around that if bought in the bulk packages.
