Variants are configured by specifying a line for every possible combination of option (dropdown menu) values. The last three positions in each line define possible values for three separate menus, so values you put in the Option1Value spot will appear in the first menu, Option2Values will appear in the second menu, etc. If you want only one menu, then you would specify a separate line for each Option1Value and leave the other two positions empty -- e.g. for your Product A:
Product A 48 States,1095.00,,,Ship to US 48 States,,
Product A Canada,1149.00,,,Ship to Canada,,
Product A Alaska/Hawaii,1285.00,,,Ship to Alaska/Hawaii,,
Note that you would still need to enable Shipping for the product to trigger collection of an address during checkout, but you can disable additional shipping charges if your Seller Admin > Cart Shipping Settings has no zipcode (this disables USPS rate lookups) and all other settings left at 0.00 on that screen as well.
