We bought a quite rare Tag Heuer watch on board for $3400. Now the thing is, we're from the UK, and at the time it was $2.20 to the £1.00. The cheapest we could find the same watch anywhere in the UK was £2800, so I reckon we made a killing. We've also found Tommy Bahamas shirts on sale too, which are difficult to find in the UK. But Invicta watches? The same as Timex in the UK.
There was a really good scam going on in the UK a while back. A company took out full page ads in high end magazines like Tatler and Vanity Fair showing their watches, with prices over a thousand pounds. Salesmen were then going round stopping people in the street from their cars, showing them the magazine ad and telling them they'd just made a delivery and had a watch left, which they could have for £350 instead of the £1200 in the ad. The watches were worth about £15.00!
