Fast-food chains are responding to economic headwinds with various promotions. Wendy's, in particular, is offering a 25-cent Dave's Single burger through Grubhub for orders exceeding $20 and a two-for-$7 deal on various menu items, both in-store and via the app. This follows Wendy's recent announcement of closing 140 underperforming locations.

Despite the closures, Wendy's has seen sales improvements, partially attributed to a successful SpongeBob SquarePants-themed promotion. The campaign, leveraging nostalgia, has apparently outperformed expectations.

McDonald's is also readying for the new year with the launch of its McValue menu, featuring fan-favorites and a new "Buy One, Add One for $1" offer on breakfast, lunch, and dinner items. John Cena is slated to front the campaign.

These promotions are a direct response to the current economic climate. Reduced consumer spending is impacting fast-food restaurant profits, forcing chains to explore creative incentives to maintain customer engagement.
