Interestingly when I tried to sign up my wife (using her cell phone) I got an error message when I tried to enter the FREEPANERA5 promo code. It said “looks like we need to verify your profile before we can deliver your gift. please contact support@bitmo.com” Is this offer limited one per person or one per household? I e-mailed support, so we will see what verification they are looking for.
On a side note, if you have to pay for your texts (I pay 20 cents each on AT&T PREPAID) they will send you at least 3 text messages before you can finish the sign-up process, redeem the $5 Panera e-gift card and delete their app.
