Possible, by right, is more than enough, dont buy excess stuff
that you dont really need, because my class dont have the brain to
plan, and usually spend out of limit, about $200+ for a pathetic
bbq. So my tips for you is, dont buy those not really need, or
extra, unless necessary. Like example, candle, fire starter, ice
cube and etc. buy just nice, cos some farker will tend to take
extra. 
Have fun!
