V festival staffs???

[lucyshandbag]

going to V festival at weston park this year and really don't want to do the hike from the car carrying my life on my back! so i'm thinkning of just buying my sleeping bag, camping chair etc when i'm there, so there's less to carry. i've never paid attention to the cost of these things there so just wondering if anyone knows roughly how much you pay for these things there, don't want to pay well over the odds for it all!
