Just remember, whenever possible, to buy by clicking through from TDP. Bryan gets support for the site this way. I don't know how specific you have to be, but if, for example, you were going to buy a Canon EF 70-200mm f/2.8 L IS II, you go to the review, click "Buy", and it will take you to the product directly, and TDP gets a small piece to help keep the site running. I don't know what would happen if you browsed away from that and bought something else, even from the same site, so I have been trying to be very vigilant about my process as described. Clarification might be in order from Bryan on this.
