I don't doubt the products. Just check the price before buying. My experience is that products can be purchase cheaper elsewhere

The merchandise is usually real but you should also check to ensure that Groupon is authorized to sell Michael Kors products. If they are not authorized then the warranty on the merchandise will be voided by if provided by Michael Kors.

I believe so.

Contact Michael kors and ask if groupon is their authorized seller

I really don't know but I have never experienced any fake merchandise. My problem is that I have closed my account and contacted CS six times about stopping the ads to my email. Each time they say they they will but I am still getting ads. Good luck getting rid of these folks of you ever decide to.

I honestly do not know about the watches. I almost bought some large diamond rings and finally did not after reading sone reviews.
I just bought a silver chain for my grandson but have not received it yet. It wasnt expensive so I took chance.
I have bought coach from their store which is from Movado brand and the gold came off and a bracelet clasp broke. They say they are guaranteed so we might try to get fixed. But I don't buy their jewelry any longer.
