With ebay it's easy, all depends on what products you're selling and how many accounts you have, if you only deal in items that have a profit margin of at least $100 and up even 50k in a month is easily doable.
I was making alot of money on there, even sold an old school BMW classic car on Ebay. My supplies couldnt even keep up with the demand at one point. What I did was sell a huge margin of a particular item that has a high demand on ebay then I went to many storage auctions and sold most of those items on Ebay too. Listing all those items on Ebay takes alot of time due to taking pictures of each item and writing a description of each one but the money is worth it. Storage auction works great for me because I only buy storages that has antique and old items which goes for high dollars on Ebay.
I need more dude. I seriously leave EVERYTHING to the last second.... if i was dying and had to take a 1 pill to save my life... ill probably end up taking it at the last second.... that's how bad it is :(
Anyone making 10k a month?
