To celebrate National Ampersand Day on Friday, Sept. 8, &pizza will be giving away free pies.
Spot an ampersand sticker, take a photo and upload to social media using the tag #MakeYourMark for a chance to win free pizza for a month. There will be 23 winners to celebrate &pizza's 23 shops.
If you spot an &pizza community manager during your morning commute and get an "amp stamp" (ink stamp) show it in-shop for a free pie. The promotion includes the eatery's newest creation, Dirty Bird, which has buffalo chicken.
There will also be balloons and a DJ at the Walnut Street location (1430 Walnut St.) from noon to 2 p.m.
