"Here are a few other cards that are free:
▪︎Chase Amazon Prime Visa: 5% cashback on Amazon purchases.
▪︎United Gateway: 25% back on inflight purchases.
▪︎Barclay's Arrival.
Alternatively, you could consider getting an Amex card with a small annual fee that offers return protection, Amex offers, purchase protection, and warranty benefits.
Another option is a Chase Simple card, such as the Sapphire Preferred ($95 annual fee). It includes $15 quarterly credit for Instacart, worth $60. (Do lacal stores to avoid extra IC fees for pickup), extended warranty and purchase protection. It also offers benefits such as Gopuff and DoorDash credits, sign-up bonus, and $50 hotel credit for any hotel booked through Chase UR.
In my opinion, there are many cards with better perks than C1.
Edit..
Seems this card is pretty decent.
