>> here is an e-mail from christina. i own a busy business sharpening knives and tools. a good decision to have internet store. how do you go from retail to implementing an e-commerce component? ideas? >> well, i'm not sure if she's looking to extend to selling knives or looking to have the service going through, where you're mailing things back and forth at the postal service. if it's that, sounds like it might be that, you've got to remove the barriers. people aren't used to buying shoes through the mail until zappa made every possible. returns, doesn't fit, send it back. no harm, no foul. or dollar shave club. look at that. razor blades in the mail. >> in a box, put your knives in here. sending you the box and ship them back to you in two days. i'd send my knives out to get sharpened. >> and take away the need to drive somewhere and drive back. >> exactly. how does she get the first customers?
