That works :) Thanks so much Linda :)

Now I just have one last question...

I have two different drop-shipping rates for different products (say A for $15 and B for $35), and then use Per Item for the products I stock.

So, when a customer has any number of drop-ship A in their cart, Flat Rate #1 at $15 will be the only option available. The same goes for each of the other products - Flat Rate #2 at $35, Per Item at $6, etc.

I want to have just one shipping method as the only option, no matter what a customer has in their cart, but this next part is confusing me as to how to get it to work:

If a customer buys one of each of the drop-shipped items (A and B), Flat Rate #2 ($35) would be the only option.

And if a customer buys either of the drop-shipped items (A or B), combined with products I stock, then the respective shipping rate would show. For example, if a customer buys an item from A as well as items I stock, the shipping would be Flat Rate #1 at $15. If item A was changed to B, then the shipping would be #2 at $35.

How would I get all this into the code?

Again - thanks so much for your help. I REALLY appreciate it :)
