Good point. And this is exactly why I put pricing in my ads. I advertise widgets as an affiliate of the biggest widget-seller on the Internet.
They do NOT have the best prices, but they are well-known, convenient, and have deep stock. Some other affilities avoid prices, and tout 30% off, great prices, etc. I put the price in the ad, and negative keywords for "cheap" etc. If they are price-shopping, I want to scare them off. They are not going to get the best prices from this store.
Here's the price. If you don't like it, go away. Please.
