PURCHASING SUPERPOWER

A recent conversation with a bank manager revealed a previously unknown fact to me: You should have multiple credit cards, apparently so you can build a reliable credit history to get such as a home loan or whatever. Just one's not enough. I've been thinking about getting another one (the one my bank offers seems like a pretty good deal) and using it to only buy very specific things. But what? CDs? Comics? Pineapples? Every month I could buy like one pineapple a week and pay off the bill promptly. What kind of consumer picture does that paint, I wonder. "I guess ... I guess this guy really likes pineapples." Maybe I'd eventually get a deal on pineapples. All the pineapples.

Is there something else I could be buying.
