The problem is that we already buy from them so they have no reason to put themselves out. If you want a parts vendor you need to find one that could gain business from showing up at the show.
Not sure that I agree with them... its called the 'upsell'.
"When you buy your pieces and parts from us, did you know that you can also get your X, your Y and your Z from us too? You might now have known, but we ALSO carry these fine products that are useful to a DIY enthusiast."
What is missing from an online store is the browsing experience. If they brought "samples" of their various tools, solder stations, ardrino (sp?) and gizmos... they'd get a big boost in their sales -- at least I suspect this.
