Sorry, I'm lost in translation, what is a grill ? something that is commonly called a BBQ (gaz, charcoal, ... ) for outdoor use ? or something else ?
You are out of season.
You might be possible to find some at the bigger hardware stores; or at the smaller kitchen appliance stores (for bbq like the big green egg); but again, it's not the season and they probably will not stock them until spring (march, april).
