Prime is now $100/year.
But it includes free two day shipping as well as videos and music.
I had over 80 Amazon orders last year, more than a dozen in December alone. I use the two day shipping to send presents to family members for multiple occasions, including, for example, Keurig K-cups to my daughter in medical school, Legos to my nephews for Christmas, and shooting supplies to my brother.
I do shop price, and when Amazon is substantially more than other vendors, or when Amazon doesn't carry a product, I go with other vendors. When I need something that day, I will shop and buy locally.
I've been able to get a good price on car parts on Amazon, and the net cost of shipping, when amortizing the Prime membership over all my orders, is less than the cost of driving my car to shop for that item.
When you consider the value of my time that I save in being able to shop and ship with Prime, it's a screaming deal.
Confidentially, I ordered some watch band pins, a set of electronic shooting muffs for my wife, and a Garmin mount, just before logging onto BITOG. They will arrive Tuesday, and saved me the time and gas looking in three different stores for those things.
And given my historic order patterns, that savings in time and gas cost about $1.00 of my annual Prime membership.
