When you're searching for legit work at home jobs make sure you search for reviews about the company that hires people to work from home.
One red flag to look for is that if you have to pay anything upfront to get started with the work from home job then it's most likely a scam or just a pyramid scheme.
One work at home scam that claims you can make money but doesn't really work is the stuffing envelopes at home where you pay an upfront fee of around $35.00 to $75.00 then they send you a kit in the mail with a flyer you make copies of and then stuff into envelopes and mail those flyers to people on a mailing list and if the other person falls for the stuff at envelope pyramid scheme then you make a commission of around $5.00
It's not really a scam per say because if people signup for it you can make some money. But be aware that not many people fall for the scheme and you will most likely lose money doing it.
There are some legit work at home jobs you can do as a stay at home mom such as freelance work, blogging, writing articles for other blogs and also doing data entry or running an online store through ebay or shopify.
