We use our Prime subscription all the time. Even on everyday items. If I can make a few clicks and save myself a trip to the store on stuff I don't need right this second, I do it.
Now, if only the grocery option was a little better. You can get groceries, but I don't think the same great shipping applies.
Although we do get some specialty items that are non-perishable there.
I have been on Prime since it started.
-Dog Food: Can’t get it cheaper in my local grocery stores. Get two bags at a time, free shipping. yay
-Video: I have found so many BBC shows that i had not seen. Already get my money’s worth there.
-Grocery subscriptions
The dog food free shipping pays for prime in about 4 shipments. I get 8 a year.
