If you're looking for a credit card with a generous introductory APR period and no annual fee, you may be considering the Wells Fargo Reflect Card and the U.S. Bank Cash+ Visa Signature Card. The Wells Fargo Reflect Card is the better option for extending your interest-free period, offering 0% for 21 months on purchases and balance transfers.
In contrast, the U.S. Bank Cash+ Visa Signature Card is ideal for earning cash back, with a $200 bonus after spending $1,000 in the first 120 days and 5% cash back on two categories of your choice.
