Labour on DVD

I was in a dollar store today looking for a birthday card for my grandfather. As I was leaving the store, I noticed a rack of DVDs for sale near the door. I took a quick glance and saw "Hoffa." Intrigued, I continued to look. Much to my surprise, I found "Norma Rae (Collectors' Edition)". What are the chances that two well-known labour union movies are for sale in a dollar store? Oddly, the were $7.99 each, and not the typical $1.00.
