No change in cost? It's $6.50 altogether - $1.50 for drink and fries, and about $5 for the double QP (40% off deal). The app limits you to one deal per order every 15 minutes. The 15 minute timer starts when the order is placed, however, and they may make your food early but not usually for fries and a drink. So you place the 2nd order after you pick up the first so you can use another deal to order the sandwich, once the timer expires.
