I have been using Amazon since 4 years, I never faced any problem except buying for worth 500 for free delivery. As before I started to shop online for my baby a week ago after adding to cart products worth 500 it says my prime period is expired and I have to renew it by purchasing 499 worth prime membership. Donno what’s wrong with the the site, what made them to do so. May be of the demand the site has is asking its customers to take membership. It’s bad
