I've got Amazon Prime and recently agreed to slower shipping in exchange for a $5 Prime Pantry credit. I didn't need my order right away, so I figured why not get a free $5? So then I clicked over to find out what Prime Pantry is. I was kind of dismayed to learn you have to order 5 items to get free shipping and you can't stack the credits, you can only use one per order. The items all seem to be about the same price as what I'd pay at my local store. So I can't figure out why I would use this service? Why would I order these items from Amazon instead of just picking them up the next time I go grocery shopping? It's ground shipping so it's not a convenience thing, like I have a busy week so I'll order some groceries and they'll be delivered in two days.
So, has anyone found a good use for this? What am I missing?
