How much have you earned from ebay.com?

I have owned a ebay store for about 4 months now. what i do is frequent different types of auction , try to get collectibles relative cheap and sell them through my store on ebay. At first I was only making a couple hundred dollars here and there. once i got down i was able to generate about 2500- 400 a month. Of course this flucuates a bit. I will let yopu know that this is not as easy as the many program and kit they sell on the internet. It takes quite a bit of research and footwork to make this profitable.
