You never did say if the check was any good, was it? or did it bounce?
I had a company called Tagzz (webbased company) stiff my company for card printer($2,000), sent the check, company received it but it was made out incorrect, once we got through to the owner he said sue him, of course my company wouldn't go through the legal process. Another company House of Brussel Chocolates, you can see their stores all over in malls etc., stiffed us for $ 1,500 in ribbon supplies for their thermal printer. Another painful experience was helping out a company test a thermal printer with their software, it worked after assisting them getting drivers setup correctly, software configured correctly, they returned the printer then purchased it elsewhere - they kept the power cable (Snap On Tools). The printers were low margin product about 10%, the ribbon was 25% markup.
