Be careful about “too good to be true” ads on Facebook!
Even when the ad is not “too good to be true,” how do you know it isn’t a scam to get your credit card number? How do you know you will get it?
I use PayPal when I order anything online. If I don’t get it and can’t find the merchant or get an answer from customer service, I open a “dispute” with PayPal customer service. I have never not gotten my money refunded from PayPal.
