What can you get for a dollar these days? Not much, except for something off of the McDonald's Dollar Menu. Now add to the list Old Navy flip flops! This Saturday only, head to your local Old Navy store and get as many flip flops as your feet desire. Red, yellow, blue, green, purple — have them all for one dollar each! Don't forget, once Saturday is over, the horse carriage (aka your flip flops) turns into a pumpkin (aka are regular price again).
