Read our customers' feedback:

I was very happy with the container I bought from Superbox. It was the cheapest I found and delivery was on time and professional.  Sarah was a pleasure to deal with.

These guys are top notch we have purchased 6 containers from them already and always delivered on time and containers are always as described. They even do our container moves for us from Job site to job site.

This is the 2nd container we’ve purchased from Superbox Inc. to store in our church parking lot. Sarah has been amazing to work with and also great delivery drivers dropping the container right where we wanted it…
