- It's relatively cheap. ($2.24 for Engineer's Guide and $4.95 for Independent Cycle Touring
- Daily pick up from my mailbox, even on Saturdays. This is pretty cool.
- An unlimited supply of free envelopes for Independent Cycle Touring. Having to pay for my own envelopes is one reason why I have to charge $3 to ship Engineer's Guide.
Little details like this is what makes fulfillment challenging. It really gives you respect for on-line retailers like Amazon who do this all the time for millions of customers.
