They have the worst customer service. I bought a $130 plus tax litterbox that was self cleaning. I; m disabled so I thought it would be great. When I got it I had to try all the tricks they offered to get my cat comfortable with the new set up. He is a large cat and his poop is as big as my Pitbull's. His urine is also a large amount so the box is basically unusable to him after 2 or 3 days. Not even close to what was promised. Of course it was after 14 days and Groupon would not do ANYTHING. I will say that the company i bought the litter from gave me 75% back and called me to talk about it. The company I bought the permanent pan from gave me 50% back. Both of them were so nice. Both were sellers on AMAZON. I am on a very small income now that I can't work so it's really hard to take the hit for this. Groupon did not care about my situation or the fact that they lost a customer who has bought a lot of products from them. Very disappointed.
