Pico de Gap Truck giving NYC, LA, SF & Chicago free tacos.

The Gap, America’s basics brand, has cooked up quite the tasty promotional idea. Now through September, the above baby-blue taco truck will be out and about in New York, Chicago, San Fransisco, and LA selling delicious tacos for just $1.69. But if you bring a receipt proving that you bought something from Gap’s 1969 denim line on that day, you get your taco free.

Um… yes, please.

Gap’s Facebook and Twitter page has everything you need to find one of the trucks.
