I had come to Staples to get something printed for me and remembered I was almost out of the white boxes I use for storage etc. The gentlemen at the printing counter wasn’t waiting on a customer and since I walk with a cane offered to get them for me as they are very heavy. Above and beyond the call of duty and I thanked him very much. Also got my printed material from a lovely young lady who had made suggestions for what I needed and I was very pleased. Everyone was so helpful and considerate. A good shopping experience.
I am using these boxes to clean out a home to sell it. We have used the boxes for everything from books to dishes to general household items. I don't know if they would hold up in unairconditioned damp conditions with heavy books in them for years and years. You might want the slightly heavier boxes if that was your purpose. We have loaded these full with heavy books and they do fine for the transporting. The boxes aren't huge so that keeps the contents from getting too heavy. They are easy to assemble and don't take up much space while not is use. I recommend just getting these (watch for sales) and skip trying to go to lots of places gathering used boxes. There is some cost involved but it saves your time and gas running to multiple places dealing with the space issues of pre assembled boxes lids etc.
