When you reach the limit of free storage (i.e., 1GB for Picasa Web Albums, 2.8GB for Gmail), consider this your overflow solution. Plans start at $20/year for 6GB (yes, $5 cheaper than before), with larger plans ranging up to 250GB. If only testing everything were this easy.
(I wonder, then, if this guy got his for free.)
WebmasterWorld members are happy that Google is offering such a solution, but the price is a bit steep for online storage. Hopefully, they'll lower prices soon enough.
