<p>The refunds don’t have much rhyme or reason in my case. I got $2+ from Apple, $4+ from Amazon and $14+ from Barnes and Noble. I don’t remember buying more than one book from Apple but I buy frequently including textbooks from Amazon. I used to buy from B&N before we signed up for Prime so that now seems reasonable. I don’t understand why my Amazon was so low unless it is because I mostly buy books on sale (except for the textbooks).</p>
