When was the last time you were in a bank branch? For most of us, the answer is: not for a while. This is one of the primary reasons for why online checking accounts are popping up and becoming a popular choice for people. Since companies offering online checking accounts don’t have to pay for the operating of a bank building, they can offer more perks to customers. Some banks even offer incentives such as huge cash bonuses just for opening a new online account. It is common to be offered $100, $200 and even over $400 for new account sign-ups.
