Well, we've -- of course, we have shipping source, because we've had to. We haven't had a choice. I think one of the ways we cure for that is as I said, we do intend to expand into somewhere in the middle of the country. It makes a lot of sense for us to be there from a whole host of it, less expensive to do business, easier to expand, trained workforce. I believe we're going to be heading into a recession. And I think if you look at the employment numbers right now, although employment numbers are still increasing, most of them are in service and hospitality, in this kind of skill sets that we choose. I think we're already starting to see a decline there and there'll be a lot of people available for us. So that we will save money that way. The percentage costs are so varied depending on where we're going and whether or not we self-perform or how we would -- so just to be clear, sometimes we deliver ourselves using our own equipment, sometimes we use third-party carriers and sometimes our customers do the delivery. And so, we don't even do that. So, they're very varied. In no instance, they prohibitively enough to prevent us selling and deploying the product, but we would certainly love to bring these costs down. And what I'll tell you is, we have seen as much as 5x decrease in cost. For example, the shipper container, across the Pacific Ocean from where the battery cells that we buy still come, 5x reduction in cost, dramatic reduction in cost to move a truck across the United States. And even more than the cost reduction, where last year for [indiscernible] be able to show up this time last year, because they were so busy. Now they're calling us looking for loads. And when trucking companies are calling you, looking for loads, two things going on. First of all, they're moving into a recession at some point or something that looks like one. And the second thing is you pay a lot less. Now, where recession is concerned, I want to be actually very clear about something. We have absolutely no top-line risk to right now from recession. None. But I don't think it might go the other way. I think it might do even more because infrastructure build outs and so on will be so important. But at the same time, I do anticipate a continued and even more dramatic reduction in our cost moving forward as a result of reduced demand and the slowing of the inflationary environment and whole host of other things like that. So, we never want these things to happen, but I think we're in as good position as we could possibly be, if something like that does come down the pipe.
