Trying to sell videos and packages without using member areas

Hello, I have never built a website before and I am trying to figure it out. I purchased the highest membership to squarespace because I need to be allowed to sell subscriptions since I am a personal trainer. However, I am also selling packages. I am selling PDF's of my workout plans, and videos. I already set up a member area for my one on one training since that is a subscription, but all the other ones I am selling are one time purchases. Do I need to make separate member areas for purchasing my PDF's and videos? or can i sell those as products since they are one time purchases. Please help!!!!!
