I just used PWI for the first time at Michaels. I can't recall which store or fast food place I went to last week but I realized afterwards that I could have used PWI. I always use at Wal-Mart, I'm just not used to using it at other places.
I used to use it a lot more before they made it debit card only. We have 1 credit card that we use for EVERYTHING and pay it off weekly. I wish they would bring back the credit option!
I tried PWI a few weeks ago when iBotta had the $15 cash back offer. I was at the register and couldn't get it to work. There was an error. I should probably try again.
At Wal-Mart I have better luck using PWI at the scan n go (self) rather than with cashier as I have had instances in past where cashier does not scan correctly (it's just using a gift card but they use the wrong button on the cash register somehow).
