On August 10th, 2016 OneDrive free storage is being cut by two thirds…
Just to be clear, that is 66.6% less free storage!
As evil as this may be you may get an offer for a free year subscription to Office365, which comes with 1TB of online storage and is pretty cool.
What you need to know:
Office365 comes with 1TB of storage for 69.99/yr or 6.99/mo for a single user
OR
99.99/yr or 9.99/mo for 5 users
BUT if you just want extra storage it is 1.99/mo for 50GB (no yearly rate available)
The best of these deals is 5 users at the yearly rate.
