I'll gladly tell you whenever I buy things. My checking account and credit card statements are private, however (this isn't an argument against privacy, don't mistake it as such).
Here are the last... 10 things I bought:
EZPass - $70.00
Roll20.net - $9.99
Potbelly - $4.98
Gold's Gym - $19.99
Potbelly - $4.98
Potbelly - $4.98
Pearl Dive (it's a bar) - $12.90
Chipotle - $3.13
Big Hunt (bar) - $8.00
Madhatter (bar) - $13.90
If you want more, come follow me around a bit. You wouldn't be breaking any law, after all. The fact that I go to potbelly each day, have a Gold's Gym subscription, and went to 3 bars over the last few days isn't private. None of it.
I value privacy, but I also know I don't always have it.
