See if your bank can do you a global credit card which is like a debit card but seperate from your main bank account (also like the pre-pay credit cards you can buy in walmart) that you add money to when you need to use it at stores or online.
That's what I did. My husband is retired and we live on a fixed income... every penny counts and we have very little margin for mishaps. We don't have credit cards and I had to figure out how to get my vaping supplies without PayPal. I started out with a greendot card but I wasn't nuts about the reload fee. So we opened an account with our bank that we use only for online shopping. We electronically transfer just enough money from our main checking account to the shopping account to cover each order and then use the shopping acct's debit card to order stuff.
