Valve cover shipping cost

[BLOHS7844]

I'm looking for a very rough cost of shipping a valve cover about 1000 miles. Using various websites to estimate cost i got anywhere from $7.99 to $72 for the slowest shipping method. Is the actually a reliable site for something like this? How about packaging 3 valve covers together?

Thru ups you are looking at around 15-20 bucks if it is in the US
