Why zup0 is better than zup5 and zup7? These are available for reg.
zxx0 sold for $20 in 2016. I wouldn't think it's worth more than that.
myinsurancecart.com isn't worth much, a lot similar names are available, like yourinsurancecart, webinsurancecart...
The only domain worth something is 10673.com. I'm not a specialist on number domains, but should be worth at least $500.
