Last November I did an impulse buy for a Breville coffee machine on a site. It was one of those "countdown" super sales. One hour later after the purchase I contacted the seller and he refunded me the paypal... fortunately. But the site definitely looked scammy. I notified Paypal and Shopify. It's so easy nowadays to create nice looking sites in a platform like Shopify that will give a veneer of legitimacy.
Anyway, that scammy site is gone. I wonder how many fell for this one. I should have checked how soon the site was taken down.
