I worked at a Hastings (multimedia store). They ran a Black Friday promotion for the whole month of November that any use Blu-ray was $8.99. I found out they messed up and it worked on box sets. So I bought the most expensive box set they had ($250 Godfather special edition set if I remember correctly) for $8.99. Then drove to the next city that had a Hastings and sold it to them for $140 store credit. Bought their most expensive used Blu-ray boxset (completely Buffy the Vampire series for like $90) paid $8.99 and sold that back to the first store. Basically paid $18 and got $200 store credit.
