Facebook users who upload photos of themselves with a Wildberry Lemonade to their own profiles and to the Pretzelmaker Facebook page will be entered in the sweepstakes, which runs Aug. 5 through October 13.
The winner of each week's $100 American Express gift card prize will be chosen on Wednesdays, by random draw, during the 10-week promotion. Each winner will also be featured as the profile photo on the chain's Facebook page for the remainder of the week. --Karlene Lukovitz
