Just ordered the gauge from TFtestkits, but was a bit surprised (more like concerned) that, after buying it using PayPal, I was - as usual - redirected to the merchant but before I got back to TFtestkits I got a notice asking if I wanted to proceed since it was "not secure". I went on with it but now am wondering if I should have. Obviously, PayPal is secure, and presumably TF is secure also - had the usual https designation. Any idea why this might have happened? I wrote to TF for their thoughts on it. Have to be so paranoid nowadays...mostly about getting CV though!
