27 years ago, Hoover offered free international flights with any £100 purchase
Most "sales promotions" in the 90's were little more than fraud.Most of us remember the period where almost everything in computer stores were "free after rebate."  "Emachine 1997 model FREE AFTER REBATE", "Pack of 50 CDR FREE AFTER REBATE".The rebate involved you filling out a form with the original proof of purchase, sending it off, and either never hearing from them again or having it denied.  "Sorry, wrong receipt, send us the real one" but it was already gone.Now, I assume anything with a rebate is fraud.  The insight from this article is that we were right.
