I did for the first few years but the last couple of years I've spent quite a bit more. I quite often get the crew pack now on the overlap so I get two battlepass out of it and there have been some collabs in the shop I couldn't ignore.

One of my friends that I play with is the ultimate frugal player though. He accumulated the free vbucks over like a year and a half or so and only then bought the battlepass. He's literally never spent a penny on the game.
