Jim, I remember those terminals in the pods that Sears set up so that there was no one in the departments to help customers find stuff and the stores were far from self service.Were the bar codes not bold enough for the scanners or was there some other problem? I, the late 70s, I used to go to the Sears near me in the late afternoon when there were few crowds and few sales people so most of the pods were covered with vinyl pod condoms.
In an earlier experiment in bar code reading, Rich's in Atlanta entered the Discount Store Age with their chain Richway in the late 60s. They used VERY sticky bar codes on items and the stores practically gave away merchandise from poor scanning. The real nightmare came when the weekly sales pages came out. Every item that was to go on sale had to be counted then new sales labels had to be affixed to the items so that they would ring up at the sales price. When they went off the sales price and back to the regular price, all of the items had to be recounted and restickered with the regular price. Needless to say, they did not have adequate computer technology to enter item codes to get counts to to program sales prices (some term called PLU) and customers ruined some plastic items with rubbing alcohol and knife blades trying to remove the stickers. It was sad. Then the oil shock hit the economy and many things took a hit like people losing jobs and Richway and Treasure Island chains closing.
Does anyone who was in retail then remember the price freezes to battle inflation? We had to keep lists to be able to prove to customers that prices had not risen during the price freeze. The only thing it did was to prove that the government cared, although its actions were misdirected and ineffective. With the price of oil going up, the price of everything had to go up. I never believed that the vertical monopoly that was the oil industry did not fleece us but good. They did not have price freezes because they had clout in the government; hell they owned most of the government.
