I love the collecting side of things, so I only buy physical products. According to my spreadsheet I average 293 discs - new and used - a year over the past decade. A good 25-30% of that comes from ProgPower, which I save my pennies for all year.
I totally get why people go all-digital, but my brain will not let me go that route.
That's impressive. I don't buy anywhere near that much, but I'm more or less with you on the physical vs digital part. I understand why digital but I just have to have the disc if its an option.
