Paypal Tips
Do not sacrifice caution for an impulse buy
Always shop with a level head and take the time to research the item and get to know your seller before agreeing to buy. Don't buy if there isn't enough time to check for warning signs.
Use Extra Caution with High-Demand Items
Particularly around the holidays, certain high-demand items are associated with higher purchasing risks. Do additional checking, especially with computers, jewelry, electronics, and items that are sold out in stores.
Be Wary of Items with Delayed Shipment
Pay attention to the advised delivery date. Delivery dates further than 20 days after your payment involve more risk. Be aware that Paypal sellers are not allowed to sell goods with delivery dates delayed more than 20 days from the date of payment.
If It Sounds Too Good to Be True...
If it sounds too good to be true, it probably is. Ask yourself if the information in the item description sounds believable.
Warning Signs
Seller Has Large Quantity of Hard to Find Items. If a seller claims to suddenly have a large quantity on an item that's impossible to find, question the validity of the claim. Ask to speak with the seller's supplier, and use a phone directory to verify that the supplier is a legitimate business with the correct address and phone number.
