We’ve shopped through Wayfair a lot.  This past experience will only garner 3 stars for we were not informed that the lamp and lamp shade would arrive separately and be delivered by two different companies.  When we only received the lampshade we contacted Fed Ex who could not help of course.  We only ever received tracking info for the shade not the lamp so we’re not even home when it finally did arrive.
We are now waiting the 3 business days to hear back from your team about buying a diffuser for the lamp shade which is supposed to be available. Today is the third business day so hopefully will hear something soon.
Our past experiences have been stellar and that is why we continue to use Wayfair.
