The few cents you MAY save by using the card isn't worth the hassle. I stopped using it immediately after last week. Here's why.
Last week, Monday morning I log on to find I'm $-62.00 and change in the hole. I'm like WTF?? Of coarse there's no explanation from Goober. I work furiously Monday trying to get out of the hole because rent's coming at the first of the month.
Tuesday rolls around and I log on and another gas charge was taken out. At this point my head is about to explode. More money was taken out of what I busted my azz to make on Monday.
Wednesday rolls around and... you guessed it, more money was taken out from what I made on Tuesday.
An email was finally sent out stating there were some billing problems and that everything had been resolved. Great
I'm not denying I owed for the gas but to put me in the hole like that, sucked.
Problem is, they aren't consistent when they take the money out. Could be the next day or three days from today. Make sure you keep ALL of your receipts and check them against what Goober takes out. It's just not worth all the hassle for me. I stopped using it completely unless an emergency arises.
