We have three pdf files for download.
We are building two more. Our intention is to continue offering each file for a fixed price, but when all five are online we would like to offer five for the price of four.
Is it possible to do this through the shopping cart? Would it be easier if we combined all five files into a single pdf file?
Our concern is that we use pdf stamping. The combined file would be about 50-60 mb, give or take. Would it then be too large to quickly stamp? Is there a way to slow down delivery so the stamping can be completed?
We won't have the last two files ready tomorrow. It will take a while, but perhaps an answer will affect how we build them.
