In the 70s I would get the coupon from the Radio Shack brochure in the Sunday paper and go get my free 5 D-cell gray plastic flashlight. With any luck and lots of care, it would last until the next coupon came out a month later. I also had three free battery of the month cards and would hit three stores to keep the flashlights going.
There is one near here that is combined with a tire store. A friend needed a memory stick and we went there a while back. They had a 500Mb for $129.00. We passed. Checked online and he ordered a 2 gb for about $10.
