The offer is redeemable on Amazon using a promotional code -- "MOVIE99."
Google, meanwhile, requires a less catchy code, but a budget-friendly rental can also be purchased via this link.
Amazon has about 49,000 titles available through the deal, including recent releases, like "Suicide Squad" and "Magnificent Seven," and some holiday classics as well.
Amazon's promotion runs through January 23, 2017.
Both retailers are allowing one use of the deal per account.
The roll-out of the offers coincides with the start of the Christmas holiday weekend.
