$68, AL, repay $75 on 3/17, cashapp/venmo/paypal/varo, seeking loan to help with vehicle expenses

I've never done this before but someone recommended for me to try this as opposed to those payday loan apps. I will likely be able to repay sooner than listed but I wanted to make sure that if something unexpected were to happen it wouldn't interfere with my repayment window, I'd rather under promise and over deliver than the other way around.
