Since a fourteen-day free trial is apparently only really thirteen days long, and the aforementioned drop shipping network decided to charge me for a month's membership on the morning of the fourteenth day before their customer service lines were even open, I am trying one last strategy on eBay to try and earn my $50 back. I have listed a few items, and I will be listing more over the next several days, so if there are kids in your life who like books, you might want to keep an eye on my listings. I could have sworn I saw a way to subscribe to a feed last night, but now I don't see it. However, you can select "Save this search" and have eBay e-mail you as I add more items.
By the way, these drop ship suppliers only ship to US addresses, but I recently heard about a way around that for international buyers. MyUS.com lets you sign up for a US mailing address where you can have packages shipped, and they will forward them to you for a nominal fee (on average 70% less than what most US retailers will charge you for international shipping).
