Recently we went on a vacation. After buying plane tickets hotels etc we went back to nail down the car rental. It had gone up $80... Then, tried another computer and also using an IP blocking program, and the price was back was $80 less - as before. So...for all the IT guys out there: Do you have a preferred method of dealing with this? I google'd the subject line of this post, and these were interesting http://lifehacker.com/5887140/every...what-you-do-on-the-web-heres-how-to-stop-them http://news.cnet.com/8301-1009_3-57457473-83/how-to-browse-sensitive-subjects-without-being-tracked It would also be nice to be able to act like I am in the US - for example I had purchased something on ebay but was not able to pay for it while I was gone because paypal would not work in France. And strangely, when I got back it still thought I was in France and sent me the email receipt in French. I could not even call the help line as the webpage was entirely in French... Also it would be nice to have a known secure connection at the hotels. Once upon a time a friend of Kim's showed me how to tunnel into the home computer - but when we tried it away from the house the Linksys router possibly could not handle it and was completely reset after a while! I wrote this off to crappy hardware, but don't really know what caused it.
