I felt the same way. But, just to calm some nerves here, I had a Rolex Deepsea. I clicked on instant quote and epkin gave me an ok quote. At first, it took me a few days of thinking because I had no clue that once I sent it in, they'd pay me! So, I called them and spoke to a very nice lady who made me feel quite comfortable. I decided to go for it and sent it with the UPS pre-paid label.
3 days later I get an email from epkin saying that they received my rolex and the original offer was still valid. They said they would either send me an instant Paypal payment or money order (whichever I prefered). I chose to do Paypal since I knew that was the fastest way to get money. I plan on sending in a couple of my old purses soon, once I'm done with them.
