Looking to purchase a car camping pass

I bought my friend and I GA tickets, but waited a little too long to get the car camping pass. She will be carrying a heavy item, so it wouldn't be ideal to walk it to the campground from satellite parking. Her birthday is also right on June 25th, the day all the fun begins! If anyone knows where I can acquire one for a decent price, it would mean a lot to the both of us. 🙏🏽
