Update: Some offers mentioned below are no longer available. View the current offers here.The Ink Plus Business Card from Chase routinely earns a high spot on TPG’s monthly list of top travel rewards credit card offers, thanks to lucrative bonus categories and a sign-up bonus of 60,000 points after spending $5,000 in the first three months. While that offer is already worth a whopping $1,260 based on TPG’s valuations, for a limited time you can nab an even higher sign-up bonus.In honor of National Small Business Week, now through May 15 you can earn 70,000 Ultimate Rewards points after spending $5,000 in the first three months when you sign up in person at a Chase branch. That’s 10,000 points more than the usual sign-up bonus of 60,000 points that’s been around for some time now, and it doesn’t require meeting a higher spending threshold. Seen below is a Chase flyer advertising the limited-time offer, provided by TPG reader Roma M.:Current Chase offers include an elevated Ink Plus sign-up bonus when you apply at a branch.Is it worth it?Branch-only offers can be an inconvenience — remember how Chase Freedom Unlimited applications were initially restricted to customers at a physical Chase location? — but if isn’t a hassle for you to drop by in person, the higher-than-usual bonus for the Ink Plus Business Card could definitely be worth snagging. The extra 10,000 points are worth $210 based on TPG’s latest valuations, and with the spring and summer travel seasons upon us it shouldn’t be hard to put those Ultimate Reward points to use with the program’s strong selection of transfer partners, including British Airways, Hyatt and United.As you can see, this business card is an especially attractive option for those who can leverage the 5x bonus spending category, which earns an outstanding 10.5% return on office supplies and other eligible purchases. It does have an annual fee of $95, but the sign-up bonus alone easily makes up for it, as does the opportunity to earn bonus Ultimate Rewards points on a variety of spending categories.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

If you’ve been considering applying and live relatively close to one of Chase’s 5,000-plus US branches, now’s as good a time as ever to take the plunge. Plus, it’s been a while since we last saw a 70,000-point offer for this card, so we may not see this same bonus pop up again soon.For more information, see these posts:Why You Should Get the Chase Sapphire Preferred, Freedom AND Ink Plus in 2016A Year of Earning and Burning with Chase Ink PlusNew Increased Offers on the Chase Ink Plus and Ink Cash!Which Chase Ink Card Is Right for You?Will you sign up for the Ink Plus Business Card in-branch to nab this 70,000-point offer?
