There are several websites offering money to undergo online surveys, carry out online searches, and write reviews on products. To get the credit, one needs to disclose certain information to them including one's banking details. This is why you should use this route with utmost care. Some of them may even ask you to register with them before working on projects. The most important watch out in such projects is to stay away from websites offering money that appears too good to be true. Be careful while evaluating the reputation of the website as many of them could be a scam. Most sites promote businesses showing copies of cheque payments which may have been given to the middlemen only.
If you have nothing of value to sell from home then retail arbitrage might be a better option for you. Many people partake in arbitrage to earn a little extra money, and for some it has even become their full-time job. Retail arbitrage is the buying of goods at a low price and then selling them on a different platform at a higher price. Sales in shops provide ideal opportunities to pick up products for next to nothing. These can then be sold on eBay or Amazon for higher amounts, making you a nice profit.
