$99.00 a year seems like a fair price for all the services included in this membership. I order alot of items off Amazon and the free shipping is the main reason I initial chose to try this membership. Free 2 day delivery really made it worthwhile when I used it to send gifts at Christmas.
Recently I have used the Prime Now to order from Bartells, Pcc, and also grocery items off Amazon. PrimeNow is a 2 hour delivery service included in the Prime membership. I have not been disapointed. The prices are regular store prices, not marked up like my recent attempt at using Instacart. All the food is fresh, not past the due date like Instacart. There is a minimum amount which is different for each store, but it is reasonable and there is no delivery charge or service fee. Prime now can be used to order from local restaurants too(I have not used yet)
I have listened to free music through my Prime membership. Also free videos are offered but I have not even looked yet to see what's available.
I save time not running to the store and money too as I get 5% back when I use my Amazon.com credit card. To me Amazon Prime membership is worth it!
