We just recently conducted a successful Kickstarter campaign and in a few months we're going to need to ship about 800 orders, so we're starting to plan the process.
Most of our customers will be in the U.S. but many are International. The basic package that most customers will receive includes a 9x12 book in a bumper box, five 9"x12" posters, and 5 greeting cards with envelopes. We're thinking that the cheapest method for domestic shipping may be to send the book via media mail and the other items in a rigid envelope (since media mail would not allow us to include everything). But we hate to send two separate shipments if it isn't necessary. We're also wondering what the cheapest International option will be. Ebay has a system whereby you ship within the U.S. to a central station and they handle the International. We're wondering if we need to find something like this.
I'd be very interested to hear, based upon this rough description, if anyone has any innovative ideas for how we can simplify this and keep it affordable. Unfortunately, many of these books will be personalized, so this could be a very complicated logistical process.
Thanks in advance for any advice you might have to offer.
