Selling Ww On E Whatever

I am selling a small amount of stamps on e commerce. It is currently limited to the lower US 48. This is nothing more than hobby selling and not for any significant profit. I have actually had a few go for 1¢ + postage and that is OK as long as another collector can enjoy filling an empty spot in an album. So my question is - what are the pros and cons of expanding this to sales outside the US lower 48?
Thanks all for your guidance.

Well you can add Hawaii and Alaska for no additional postage costs. No problem there. The pros of selling to other countries - you can potential double your audience or more. Cons, yes and occasional order gets lost or stolen, but that rate is probably less than 1%.
