A4 vs Letter

[Live Free]

Hi, I am using CLICKBANK and E-Junkie for an e-book I sell online. However. as this is sold globally, and often people want to print it, I have had to make an A4 and a Letter version so they are printer friendly. However. I do not know how to give customers the option when they go to check out. Anyone able to help? Cheers

I'd say, don't bother with 2 sizes. Adobe reader can resize for printing.

I have my manuals in a4 and have not had a single complaint from US customers.
