To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The Amazon voucher is a great gift! My friend received the customized by me card via an email within 5 min of payment completion and could use it right away for shopping on Amazon. We are both in the same country with separate individual accounts for the same country.
It’s wonderful present for someone you have no area what he or she would like. Just be careful for which country you are perches it - for example if you are giving it to someone in Canada but the voucher is from Amazon UK they will have very limited choice of items which offer delivery to Canada
