So I'm a 17 year old kid who rides occasionally at tracks and some trails. Lately I've been thinking of some ways to earn some extra cash over the upcoming summer, and this idea dawned on me about 15 minutes ago: I want to sell items at the local tracks around here. I want to buy some inventory (grips, levers, jerseys, pants, goggles, tear-aways, gloves, spark plugs, oil, tubes, etc) and then be able to take it to the track. If I can buy any of these items at least a little bit under retail, I can resell them for just a bit more. Since I'm not trying to make a living off of this, I think I could undersell any major competition that also sells things at the track. So my questions are: 1.) Is this a decent idea? Would you purchase items like this? 2.) Are there any places I could buy inventory from, that I could then resell? (ie: wholesale or in bulk?) Thanks.
