View the current offers here – Starwood Preferred Guest® Business Credit Card from American Express, Starwood Preferred Guest® Credit Card from American ExpressA couple weeks ago, I wrote about a great sign-up bonus for the Starwood Amex card- 30,000 points as long as you spend $1,000 in the first three months. The deadline to apply was July 6, but it has just been extended to July 31.(Note- I am NOT getting paid by American Express for advertising this. I just firmly believe this is a great deal for my followers).I can’t reiterate enough how much of a good deal this is and how valuable Starwood points are in the scheme of the mileage earning world. This is a perfect card and opportunity for someone who wants to get serious about accruing miles.If you don’t believe me, check out Brad’s Deals- a popular deal blog that has been featured on the Today Show and in USA Today. They outline 10 reasons why this card makes sense (Note: number three is a different sign-up bonus. The links I provided are an even better deal).Reminder- you can apply for both personal and business credit cards.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
