Correct Offer markup for product with variants

Hi,

My name is Radu Silaghi and I need a bit of help, before heading the wrong
way.
For a product like ex. Amazon Kindle Paperwhite, which comes in 2 variants
( with Wi-Fi Only and Wi-Fi+3G ), is
https://schema.org/AggregateOffer the right approach ?


Thanks for help,

Radu Silaghi
