Please help sort this out.
I'm trying to make this as easy as possible since I'm selling 1 item for 1 week.
A 5-pack of cookies costs $7 to ship 2-Day $12 for Express.
10-pack $9 2-Day and $15 Express.
There's just 1 flavor of cookie sold in multiples of 5. A person needs to be able to go in and order, say 20 cookies overnight, and a price comes up.
I can't figure out how to configure this between the classes, items, and orders so that the shipping is fair for both me and the buyer.
Maybe I just make products that include shipping; example the 20-pack includes shipping and the buyer had better not buy 4 of the 5-pack or the price is going to be outrageous.
