Advice for new Dev - package or roll own

A little help / advice is needed here.

I am getting back into web development since before the days of nice frameworks and decided to learn Python and use Django to get my web app going. My app has quite a few e-commerce features, but the cart/ordering/shipping/tracking aspect of my app is maybe 20% of the code, the rest is based on custom business logic. My question is this:

I've done some research on Django packages like Oscar, Satchmo, Django-shop etc. heavyweight to lightweight packages. But since I have quite a bit of design that goes beyond simple cart/ordering logic: Does it make sense to learn how to integrate a new package into my design vs. roll my own? I've done shopping cart/etc before, but I would like to shave time off the development if I can. But I am still learning all the ins and outs of Django, the ORM etc. I don't want to spend 2 weeks learning how to integrate a Django package when I could just spend 2 weeks rolling my own. But maybe I'm mistaking how much work it will take to roll my own cart/ordering/tracking logic.

I have done it before in Java/jsp completely by hand, it was somewhat onerous but I am now running with the assumption that Django will allievate some of the pain I used to go through with all the BS CRUDS, home-made MVC logic I had to do back in 2001.

Thanks!
