Jane is correct - I spend a great deal of time emailing and even speaking with the publishers - the international publishers don't have the budget that US publishers have. I myself have spent over 100.00 to order 3 books so that I could review them and do a promotion just for New Zealand members. Shipping is outrageous - 30.00 to 40.00 a book - just to ship - to Canada and other countries. Many publishers have a contract with UPS, FedEx and can ship cheaply - not to mention media mail in the states where we can mail a book for around 4.50.
Since I have started working with EYB - I try to post 5 to 7 giveaways a week and I try to balance them out to include worldwide and other countries. Even EYB (Jane) will donate a worldwide title and I have donated books. Prior to my doing promotions, we didn't have nearly this amount of giveaways - so I know it must seem like some countries are left out but there are many more giveaways in the mix.
I keep negotiating with international publishers and hopefully, the market will turn around. Jenny, Cookbook Promotions Manager
