Grooming.com actually redirects to Gillette.com, so I'm actually talking to them to buy grooming.shop...
Luxuryhotels.shop I also have...and luxuryhotels.com redirects to Marriott...
That is btw a quite good thinking..when I saw results for grooming at namebio:
Domain Price Date Venue
grooming.net 405 USD 2016-09-07 NameJet
beardgrooming.com 395 USD 2016-05-30 NameJet
groomingstore.com 2,000 USD 2015-12-29 BuyDomains
vipgrooming.com 420 USD 2015-05-24
GoDaddy
groomingsupplies.co.uk 1,000 USD 2011-03-22 Sedo
petgroomingsupply.com 810 USD 2011-01-07 NameJet
groomingkit.net 131 USD 2010-02-22 NameJet
petgrooming.net 675 USD 2009-08-13 SnapNames
I was actually not very impressed, as groomingstore.com was for $2000, so not much, and it is established com, so new gTLD is usually a fraction of that.
However, that does not mean so much imo..the information that Grooming.com actually redirects to Gillette.com is very important, that means the company value this keyword. Therefore, it will be only up to your negotiation skills how much value can you extract for this. The main question is : how can this company benefit from getting your name? If you can answer that question well, you can make LOT of money, is it is huge company.
