If you want to host the lockers, you have to fill out an application. Amazon then takes into consideration several different factors to allow you to host the lockers. The questions include whether you are the owner of the property, what type of location it is (drug store, gas station, etc.), the address, and the number of locations you have available.

For longer term storage, there are many self storage units around the metro area. Not cheap, but then neither is paying extra baggage fees and lugging around extra stuff not needed for another leg of your trip, as it sounds like Terry might be doing. For example, I found "Downtown Denver Self Storage" with units starting at $45 a month. http://www.downtowndenverstorage.com/ Denver Locker
