Look after the pennies, and the pounds (or dollars, euros, pesos or whatever) will take care of themselves. Or at least, that’s what our parents used to tell us, right?
That may be sensible where traditional currency is concerned, but it’s not a strategy that converts well into MSP. Waiting for sales and bargains may be the cheapest way of buying XBLA games – but what if the game you want never goes on sale? What if everyone else has moved on and you lose out on the best bit of a fantastic co-op game like Lara Croft: GOL or a community-focused game like Section 8: Prejudice? What if you think you’re buying something you want, but actually you just bought it because it was cheap and you end up wasting MSP anyway?
