I know I am a new user and I registered specifically to post this information. Trust me, this method works. Research into it yourself if you don't believe me. Also, you can see there is no referral or anything on this page. I am giving this information for a reason I won't disclose. You can make at least $500 per day by doing this: Buy WileyPlus Registration codes (online class access codes) from WileyPlus.com (official publisher's website) and sell them on ebay. Most people do not know that WileyPlus codes are interchangeable. So if you have a Math class WileyPlus registration code (which costs $13), then the same one-time use code can be used for for an Accounting class or any other class (which cost up to $80). So buy codes from WileyPlus.com for $12 and sell it on eBay for $40 (that's how much they go for usually). Here are the steps: Step 1) Go to wileyplus.com/buy Step 2) Click on "Please click here to purchase your WileyPLUS registration code." Step 3) Using CTRL-F, find "McCallum / Algebra: Form and Function Draft Edition, WileyPLUS Registration Code" in the list. Step 4) Go through the buying process -- your total will be $12.95 Step 5) Sell this code on eBay: Search WileyPlus to see examples of other listing and the price they go for. Remember, this codes will work with any course. Make the shipping method pick up only. People will buy it knowing you will email the code. PROOF: Look at this seller feedback to see how many codes and at what price he sold in just a month: http://feedback.ebay.com/ws/eBayISAPI.dll?ViewFeedback2&userid=lxcshop&ftab=FeedbackAsSeller http://feedback.ebay.com/ws/eBayISAPI.dll?ViewFeedback2&userid=lxcweb&ftab=FeedbackAsSeller Also make a listing similar to his listing so eBay won't give you any problem with selling digital products in an electronic/book category.
