Ah, not sure if it's location specific, but as some of the posters above, I had never heard of W+ until now. I was exploring the site yesterday, and ordered some paper towels or something, and the delivery fee was waived. Slight difference is that A Prime offered overnight delivery, while W+ could only deliver on Monday. For me, this is inconsequential--if I needed something immediately, I'd go to a store.

I suspect, you meant groceries? For some reason, they don't currently deliver to my area.
