I recently got an email from amazon saying they are charging my card again for items which I have already returned to them (via the whole foods store). I even have confirmation email of the said returns. Now the email claims they haven't gotten it (which I don't care about as I was only responsible for dropping them off to whole foods). I am sure this is a glitch and I can contact them and get this fixed. However as a new dad this takes time away from other stuff and I would rather not have to deal with this. Will be more wary of purchases from now on.
