I'm stuck with a shipping problem.
I sell acrylic sheets on the site and ship via ups.
If a customer buys 1 sheet, the shipping quote works well using dimensional weight.
If the customer buys 5, the shipping quotes go crazy high when it should just be about 5-10 dollars higher as it seems to treat each item separately and the dimensional weight is very large.
How would one go about setting up a close to correct quote for 1 sheet or more?
