There seems to be more and more "issues" on Bobs these days. Maybe it's time to add a feedback score or something on the members profile. I have purchased many items on Bobs and had great luck in doing so. There is no real way to vet a seller on here except to go with your gut feeling, or not buy the item. Paypal and others offer buyer and seller protections, and most on here seem to be of good character. If you buy off of Bobs regularly, you are familiar with the guys of good character.
The big problem seems to be that you never know when you have a problem until you've been screwed. Then once you post about a problem, you hear all sorts of other issues had with that person. I'm pretty new to Karting and have met many great people on here. I just hate to see the increase in issues when the sport is struggling like it has been. It seems as though we as a collective group could handle this side of Bobs better. It doesn't do any good to trash and bash people if there is a problem. If a guy wants to sell on Bobs, his reputation should be able to be reflected in his profile. Just my 2 cents worth!!
