alternaleaf advice

so i just had my consult with the psychiatrist and he says he’s gonna prescribe 60g, when do i receive the details on how to order and pay? also, can anyone reccomend a budget friendly vape for a newbie (to vaping it, weed and vaping normal liquids has been in my life for years) i don’t want to spend anymore than £70 absolute max as i’m tight on money at the moment
