Retailers often mark down video games and movies on Blu-ray as low as $4 or $5 on Black Friday. And in this case, the quality of the film or game remains the same, whether you pay full price or get a discount.
Black Friday can be the best time of the year to purchase boxed sets or complete seasons of television shows, de Grandpre says. "They'll hit a price low that you may not see again for months or even a year," he says.
He expects to see a deal on "The Avengers" and other summer blockbusters this year -- which might go for as little as $11.
Prices fall so low for movies on Black Friday that it may be cheaper to purchase the disc outright rather than buying it through streaming services or pay-per-view options, de Grandpre says.
Consumers regularly weigh whether purchasing a disc is worth the additional cost. "Will you really watch it enough to get your value out of it?" he says.
"That's a decision people make all year long," de Grandpre says. "That decision gets a little harder around Black Friday" when the price of ownership is competitive with one-time use.
