My possessions lived in Unit A13 at Liberty Storage next to Liberty State Park for two years.
I spent about $4,000 on storage during that time, as rates started at about $150 a month and went up to $175 over the two years.
Once I worked out what I'd spent, I went and bought a garage instead. At least--in theory--I'll get back what I've spent when I sell the garage. Plus, I might end up living in it soon. Which brings to mind certain horrifiying questions. Yikes.
