Visionworks promotes its new limited-time deal, which gives customers the chance to buy one pair of glasses and get one free, in a new commercial.

The spot features a Visionworks representative standing on the edge of a canyon, with a donkey by her side, and telling a spectacled woman on the other edge of the canyon that, if she needs a new pair of glasses, she can get it at Visionworks.

Asked how she can see her there, the Visionworks employee reveals she can’t and that she simply informs everyone about this offer.

The commercial concludes with the voiceover saying “Buy one pair, get one free” and adding the tagline “See the difference.”

The deal cannot be combined with insurance benefits or other offers. The first pair you buy must be at List Price and the second pair, which is free, must be of equal or lesser value.

The List Prices are the non-discounted prices at which they offer the frames/lenses in stores or online.
