I purchased a watch from Watch Shop Ltd, the company emailed me the next day with the subject of "Watch Shop Order: Paypal Security Check". The email asked for me to verify the purchase for security reasons before they could dispatch the item. It knew my Paypal email address which is different to the address they emailed me on. The transaction on my PayPal account is currently 'pending'. Not sure if this is normal, as I have never had a retailer/store email me asking to verify my PayPal. Is it spam?
