Can I buy stuff cheap on ebay, then re-sell it on ebay again for a higher price?

Like some people sell things like iphone 4's for crazy cheap prices which is stupid, and I know that if I buy one and re sell it I could maybe add on another hundred bucks or even more! Can I, is it that easy?

Well unless you got a really lucky bargain in the first place you will probably buy it for the price all items of the type are going for

I don't see why not but if the market is cheep on ebay try reselling on ebay and craigslist, craigslist is more local and it can be sold at the realistic prices. I do that with everything i buy, sell it for more on craigslist

Greed will only bring your downfall. People can see your history, and will know what you paid for it… Unless you have two eBay accounts, and NEVER bid or relate one to the other. Use one for buying, one for selling.

Yes it is possible. I wouldn't recommend it though, if you don't make it to sell your items or you get them in bad conditions, then instead lf winning a few hundreds, you'll be alot more.

You could try but don't forget the people who make the most out of E-Bay is E-bay and Paypal (also owned by E-bay.)

You get charged insertion fees
Final price fees
fees for photos
Fee for this that and anything else they can think of.

Then once sold Paypal takes another chunk of money as a percentage of the total price paid, including shipping costs.

As for your initial idea just work it through.

You buy an I Phone for $30 and then put it back on E-bay for $100

Which phone are people going to buy? Yours for $100 or one for $30 from the same place you got yours?

Yes there's absolutely nothing wrong with doing that, if others want to sell at stupidly low prices that is down to them.

Yes, it is possible as long as you know what you are doing.
