AuctionCut

Hello I am new to ebay selling. I have wanted to make money from ebay for a long time now and I find it exciting watching an auction. I am looking to make 800 a month selling but what would be the best method of making it as extra income rent etc. I recently watched a dvd i wanted to buy that started out as 16 pounds rocketed over 3 months to 60 pounds. The dvd was limited edition and this made me wonder if i could buy similiar limited edition dvds if i timed there coming out correctly before other buyers. I could do this for anything games consoles when they are cheap then sell them on at a later point to make a profit. Is there any websites sites that cover this method of selling limited edition products or anyone who is currently doing this to make money to give pointers or tips. I am aware of this method are there any others similir to this like buying and selling concert tickets any ideas like this. The web is a big place and i have searched only a little, help would be very grateful! . Does anyone know of any companies that offer mentoring of ebay selling for a cash pay, I would love a guide or mentor to help me through even if i had to pay them.
look forward to any reply!!!
