McDonald's have a "big deal" Cheeseburger Small Combo & Cheeseburger for $6 in their app, valid from 10:30 am to 10:30 pm and ends tomorrow. Saw a notification this morning but only getting around to posting. Worse than their normal $5 for the deal, hopefully this isn't a permanent increase.
Got this today and noticed the $30 pick your own share box they have. Effectively you can get 4x big mac or quarter pounder medium combos for $30 + free to toe bag. Not bad considering a medium big mac combo is $10.30 and $10.40 for a medium quarter pounder combo.
