I'm loving my Chase Ink and Chase Sapphire Reserved cards.
Ink gives 5X points for office supplies store, cable and phone charges. Problem is I don't think they offer the same chase Ink card anymore.
I also have the Chase Sapphire Reserved Card, It give 3X points for all travel, including Timeshare MF and charges and meals. This card also gives you a 50% bonus for booking your travel in their travel portal, I use it for Domestic Air travel. There are also transfers of points to many major airline and hotel programs at a rate of 1:1. It has a hefty $450 a year fee, but offers $300 cash back annually on any travel, and the credit it instant. If you get it near the end of the year, your annual travel credit offsets the $450 fee. I got my card in late Oct, paid some MFs got the $300 instant credit, got billed for my annual fee in Dec Statement, and in January I got another $300 credit. So I got back $600 credit in the first year on a $450 annual fee. It also provide other worthwhile perks, like Priority Club membership, and Global Entry Fee paid. The sign up bonus was also great, I got it when the bonus was 100,000 points after only 4K spending, but it is now reduced to only a 50K bonus. 100K is worth about $1500 in travel, if I spend it in the portal or $1000 cash back. Enough to offset the annual fee for me for a few years at least.
I am currently sitting on over 500,000 point and I have been booking Airline tickets with it.
I never carry any balances. Only way to make the points play work. If you get a 0% interest card, they generally offer NO other perks.
The Chase Ink Preferred Business card is like the Sapphire in its earning and points portal, but it offers a 25% bonus for the portal, it is offering an 80,000 point bonus after minimum spend in 3 months, and its only $95 a year (might be waived the first year), that card might be the one to consider right now.
