Mail/ Ordering Online

When you’re on the road, do you buy products online?
If so, how do you get your mail and what kind of things do you buy? Eg. Clothing, van parts, tools, hobbies

If it’s amazon and you’re near a city you can get smaller items in their drop boxes, sometimes that can be a pain if it’s always full. We get packages delivered to the ups store for pickup, but that can cost $5 to $10 and I think has to be less than 50lbs. I am not sure about the USPS or if they have any fees associated.
