Select an item you wish to purchase.
Do your research .. in other words is ebay cheaper than ordering online from any internet sites/shops.
Goggle a search for a particular item you want and compare prices.
Dont get into a bidding war and pay over the odds for an item
Only use paypal .. at least you are covered
Don't use bank transfer ,, scammers love it and you lose your money
Check sellers feedback and "goofbay" their feedback and history
Buy a phone from a high street store
Never buy a car off ebay , if you do get an AA or RAC inspection done if its a lot of money . Always view the car before you bid and if genuine seller he will let you test drive . Check V,I.N numbers on bulkhead and inside car .Always check under mats for a cut and shunt .. a weld that runs from one side to another .. this is a sign of 2 cars welded together , also check for overspray in boot and behind the rubber trim on weathershields .
DO NOT BUY high value items from new sellers
I have found one scamming seller .......ozarkpcs .. they currently owe me $471.95
