Up to 35lb is a lot for a digital scale so like the poster said above me they can run for quite a bit.
Do you really need something that weighs 35lbs? If you ship something that heavy weekly, it's worth it. But if it's once a month you can use your bathroom scale for that. That's what I used for the longest time. Now I have a better scale that can weigh more.
Then you can get a digital scale for cheaper.
Check Ebay. Maybe you can find a used one for cheap.
