I bought some cheap "Ray Ban" aviators on eBay. Now, I knew they'd be fake - I'm not totally stupid - but I'd hoped they'd be alright sunglasses. However, I think they were a touch overpriced for the quality, so I emailed the seller.
"These are fakes"
"No they're not! They're RayBan USA! Not made by Luxottica!"
"Bausch & Lomb haven't made RayBans since 1998. Also your packaging is stamped "Sunglasses by Luxottica". And the logos are in the wrong place for RayBan USA - here, I have a pair of genuine B&L Ray Bans, want me to compare?"
Silence, so far ;) I'm thinking I go for negative feedback, but any more creatively unpleasant things I can do? I don't mind buying fake shades, but I don't like stupid sellers who think they can fool me!
