e-bay is just an auction hosting service. You can find real and fake anythings on it. Go to e-bay's web site (assuming you mean Ontario - the province in Canada): https://www.ebay.ca/ Then type "Tamagotchi V4" in the search box and click the Find It button. Look for items (1) marked as Bandai product, (2) from sellers with lots of good feedback, (3) that you can buy using paypal, (4) that are NOT located in China.
