Today I used this app for groceries, app stated they couldn't authorize my cc. I tried again and again said it wouldn't go through. Checked my bank and they charged it twice! Called heb store who would fullfil my order, they had no record of my order. I had to call my bank to remove both charges, sat on the phone for over an hour. Tried to submit an email through their heb help site, and it wouldn't work!!! BEWARE! Btw I was on hold for over an hour for their heb toll free help line! Ridiculous
