From BundleHQ: What would you like to upgrade?

Yum, train cake. Also, I try not to get political here, but in light of a report today that more people identify Barack Obama as a Muslim today than they did two years ago, I just think this bears saying: Barack Obama is not a Muslim. Although I guess there's a bright side: if those numbers keep rising and he gets re-elected in 2012 anyway, then I think it's very progressive of this country to have a president that most of the voters think is an African-American and a Muslim. Even if half of that is not even true.

This hurts me more than it hurts you: Way back when credit cards were routinely declined, there was an American Express commercial that portrayed such a denial as a crushing embarrassment. (Subtext: AmEx would never let that happen to you. Get an AmEx! Ahh, advertising.) Today, though, as the country nurses its overspending hangover, a new service actually promises to decline your card if you bust certain self-set spending limits, Greg reports. Hallelujah, says Megan: Where do I sign up? But other Bundlers aren't so sure. Barbara wouldn't want her card declined even if she was over budget, and Kate wants to know, "Where's the catch? A credit card company has little motivation to actually let you control your spending - and then conceivably pay them less interest."

Our love-hate relationship with coupons continues: Justin's searching for online deals; Kate's into eCoupons, but wasn't it just last week that we acknowledged how coupons and deals make us overspend? And yet, the lure is irresistible. How will we ever triumph?

For love or money? For the brave Peace Corps volunteers willing to spend a couple of years in developing countries digging latrines, building schools and staffing clinics, the economics aren't bad, Emma reports: After two years, volunteers "graduate" with $7,425 in the bank - which is on top of the annual salaries/stipends they get while in country. Put another way, if you were in a job making $50,000 a year, that'd be a 7.4 percent savings rate - not bad at all. Kate points out that the program also pays for plane tickets home which, if you're flying from Ethiopia to Chicago, can cost more than $1,400. That said, it's hard work under difficult circumstances, says Megan: "I think if you're doing it for the money, you're doing it for the wrong reasons."

No love for the penny: Bundlers said yesterday that yes, the U.S. should stop minting the penny. OK, fine. But here's my question: Would you truly pay a nickel for a gumball?

In the Weekly Bundle: The most popular products in America, personal finance on napkins, and why we like making fun of public radio. You'll get it today if you've signed up for our newsletters in the box on the right, or you'll just have to wait until tomorrow.
