Prices? What prices? Doesn't Google give out everything for free, one may ask?
Relax. We're talking about extra storage; for example if free storage that comes with Picasa Web Albums or Gmail isn't enough for you, you can purchase extra storage space for a price.
Today, Google is dramatically slashing that price. You can now buy 20 GB for $5 a year, which is pretty darned cheap compared to the old price: 10 GB for 20 bucks per year.
Furthermore, Google has increased the amount of storage you can purchase. If you have a lot (we really mean a lot) of family photos, you can store them all at Google's servers in the clouds, as the cap is now 16 terabytes.
