Depending on where you live, you may want to pick up some Xbox Live membership cards soon.
A number of countries are seeing their Xbox Live prices double or even triple as Microsoft makes "adjustments based on currency inflation." Game Informer has provided a handy list:
South Africa: going to R159 per month (a little more than $10 in US dollars).
Hungary: 2,000 Ft (Approximately $7.19 per month)
Israel: 37.99 ILS (Approximately $10.05 per month)
Sweden: 79 kr (Approximately $9.58 per month)
Turkey: 18.99 TL (Approximately $6.40 per month)
Austria's price is going up as well, but just how much isn't confirmed yet.
I get my renewal cards here, if you're interested.
