Stamps and cash you may save, but it'll do you no good if you're crushed by the giant sign when it finally topples over.
The chain is still around. Says wikipedia:
Grand Union started as the Jones Brothers Tea Company in 1872. By the 1930s it was one of the largest grocery chains in the United States. The name "Grand Union" was inspired by the desire to "unite shoppers with low prices in a 'Grand Union of Value'" as described by company associate Elvin Sanders.
The store's mascot was Abraham Lincoln wearing a deli apron.
