Interesting Grubhub Credit DP
So my wife and I both have our own palladium cards. Today she wanted to order some lunch. I had already used my grubhub credit this month and she did not have a grubhub account or the app installed on our phone. I told her to go into her bilt app, redeem $10 bilt cash, for the grubhub credit and text me the code.
As I'm ordering for her I get to the point of where I apply the promo code, then I get a notice saying this promo code has already been used. That's weird this is a brand new code we got just 60 seconds earlier.
I then grab my wifes phone download the app, create an account for her, and proceed with the order again. Sure enough the promo code goes through just fine.
Do with this info as you wish and YMMV, but I strongly suspect the Bilt cash grubhub promo code is a universal promo code for that month that is limited to one use per user.
I could be wrong about this, but to me it certainly looks that way.
