Sams club offers their members 1 Free fresh item(Croissants, 16" Take n bake pizza or Rotisserie chicken) when you install and checkout through their Scan & Go app.
Saw it advertised in my club but participating stores may vary so highly YMMV. If you see it advertised in your store you should get a voucher straight away which you can use to get the free item provided you checkout with their app.
