I'll routinely buy small purchases like a coffee with a debit card. Right now I have cash and my phone on me but I usually don't have cash. When I do use cash it's for certain things. Like when I'm out with friends at a bar or dinner.
hmm, I feel really dumb. Step 4 for me is billing details and then step 5 is where I enter card information and at the bottom it says process your order. Is it after this? This seems like the last step so I don't want them to charge my card.
