Sorry for the late reply.
Here's my situation, maybe it'll clear up any doubts. I am looking for a place that will be used mainly so that our customers can pick up their merchandise. I don't want to pay monthly rent for space that won't be used daily.
In a virtual office setting you receive the amenities of a real office without the need to pay all those additional costs. You're basically paying for the appearance that you have an office in a building.
