Because the database is maintained on a daily basis rather than us doing all the work at once each year, we can generate a file for the printers in about 30 minutes. So the only constraint is the printers lead time. To be honest we were a week later than preferred, hence they wont ship until a week into June rather than maybe 5/31.

I didnt add the shopping cart code to buy both books, as the 'checkout' is shared with ebay & amazon and we cant list the new book there until it is actually in hand (Amazon will only allow pre-sales if you are a big book retailer), so I wont add it until the books have physically arrived.

Sending the extra $11 back in a few minutes

What is 'spare time'? Ive never heard that expression.
