As a variant of this offer, there exists something called Rikskuponger, which usually are food (lunch) coupons bought by a company to give to their employees. There is some tax deduction for doing this. Around the time for the first campaign, Handic sneaked in a special coupon to the 250,000 users of Rikskuponger; if the customer bought a C64 and sent in the coupon and warranty papers to Handic, he got games worth 500 SEK. It was not possible to combine with trading in a Monopoly game to get another 500 SEK worth of games though.
A fun bit of trivia. I wonder if Commodore dealers in other markets tried similar gags once the computer business was big enough to pull it off.
