The reason I don't set it up for Free Shipping is that shipping costs vary from country to country and that would make it unfair.
I think everyone knows that Free Shipping is not really free.
I'd recommend Combine Shipping.
In fact, shipping costs are almost the same whether one or two items are shipped.
Shipping only one item would be more expensive.
So I still recommend bundling.
If you have paid extra for shipping, I will refund the excess.
Please do not worry.
Standard Shipping(tracking & small insurance)It takes 7-14 days.
Expedited Shipping(tracking & perfect insurance)It takes 4-7 days.
