Don't order from them a lot (maybe 3-4 x/yr), but I've noticed lately that if you get the "free" standard shipping your order seems to get shipped when they get around to it. Ordered a couple things about a week ago, and when I log in it shows that the order has still not shipped. WTF?? Seems to have coincided with lowering the qualifying order amount to $25.
I get that not everything is stocked in every warehouse, but it would be nice if they showed what items were in the same warehouse like Rockauto does so you can plan your order accordingly.
Living out in the boonies I don't expect next day delivery, but taking a week to ship something???
We'll see how Amazon does with it. On-line grocery shopping has been tried and flopped several times over the past 15 or so years. As you noted, most people want to see the merchandise...especially perishable stuff like meat or produce. Maybe if you lived in a large city like NYC where many people don't drive...
Then again, if it takes them a week to ship your order like it does with other stuff...ewww!
