Here is a vintage Caldor newspaper ad for Atari and ColecoVision games. This ran in the Poughkeepsie Journal on Friday, March 11, 1983. I think it's interesting that they're advertising Donkey Kong for Atari 2600 in the ColecoVision section. It was a Coleco product, but better suited in the Atari section, not mixed in with ColecoVision games. That seems like it would be confusing to some. My first thought was "Why would they be advertising Donkey Kong on its own if it came with every ColecoVision sold?" Then I saw it was for the 2600. Also notice that by March, 1983 E.T. was already marked down to $14.76. E.T. had retailed for around $40 during the 1982 Christmas shopping season only a few months earlier. That's quite a price drop!
Caldor was a discount retailer that was popular in the North East during the 1970s and 1980s. Caldor could best be explained as K-Mart dressed up to look like JCPenny. The interior of each Caldor store was designed to look more like a department store than a discounter, and many were even designed by the same firms used by more up-scale retail environments. They featured wide aisles, bright lighting, and large, colorful display treatment, and were typically remodeled every 6 years. They were best recognized for "The Caldor Rainbow" with a mix of brown, yellow, and orange. Caldor struggled to compete against Wal-Mart and filed for Chapter 11 Bankruptcy protection in 1999.
