Why Do They Ask Twice?

When I order some item on line, they ask for an email address, then immediately ask for it again. Does anyone know what is behind this? Does it do something electronically which affects their computer record of it, or what? This requirement seems widespread, if not universal. Thanks. Frank

 

I. had that happen today while ordering a book @Frank Sanoica
I personally think the reason is to double check , you have added it correctly

 

They want to make sure there is no typo in your email address since they can vary in form a lot.

 

yep that's the reason...simply to ensure you've entered your address correctly the first time...

 

Gracias!
