xbox360 and Zune points expire?

[WEWdeadeye]

Yeah, free points and promotional things a long those lines (like free gift cards for X amount at certain stores for buying certain products) have almost always expired eventually. What pisses me off is when you pay for a gift card and it expires. Seems to me like that sort of practice should be illegal...why do you have to spend what basically amounts to cold hard cash on their terms? Bullshit practice that won't stop anytime soon.
