Alignment of products in shop

I am setting up a small store to sell 2 types of tickets to an upcoming event. So there are only 2 products in the store. I configured the store to only have 2 columns. The store page has some text I added on top, but the 2 products are up against the left side of the screen, way off center, with no margins. It looks sloppy and unbalanced. Is there a way to get the 2 products to be centered on the page?
You can see my store here: https://gunksclimbers.org/gunkclimbers-store/

Thanks!
