I never get an eye exam at Target before. But i saw an review at yelp.com. reviews says that it is normally $45, or $65 for an exam with pupil dilation without insurance. And i also heard that the average cost of taking eye exam at Walmart is about $50. From this point, they are almost the same compared with the prices for eye example. So, which one you choose depending on your personal preference.
It is said that it will cost you $65 for an exam with pupil dilation without insurance at Target. The common price is about $50 which is almost the same as that in the Walmart. Thus, you could choose whatever the one you like to do the eye exam. Before you want to wear the eyeglasses or contact lenses with prescription, you'd better do the eye exam.
