I'm starting this thread to try to get more people familiar with stormrider's sellbuddy software. It's easy to set up and use, I am currently using it for my FPH2 light kits. The software keeps track of current inventory, shipping information, and generates automatically a Paypal invoice for the buyer. There are a few videos on YouTube on how it works, and whether you are an established seller or a new one, sellbuddy can make it a lot easier.
i highly recommend checking out the videos and giving sellbuddy a try. It works and it helps out a fellow TDH member (SR wrote the software and spent a lot of time, energy, and money to get it off the ground).
