There is an ultimate LEGO Expert-level Ultimate Millennium Falcon that I occasionally like to drool over. It has over 7,500 pieces, a detailed exterior, multiple interior areas, and two different minifig crews (Episodes V and VII plus a porg from VIII). It is almost three feet long and two feet wide, weighs over twenty pounds, takes a couple dozen hours to build, ... and it costs about $800 dollars!
The other day, Facebook showed me an ad with it listed for $95. It listed the piece count and dimensions, but as much as I really wanted it (REALLY, REALLY wanted it), I decided to Google the company offering it. As I suspected, it was a scam company, but not in the way that I thought. It turns out that some international companies are creating LEGO knock-offs and selling them in look-alike packaging. Not being LEGO, they do not hold together well, are of dubious quality, and occasionally get lost altogether enroute. Interestingly, the company I looked up also sells knock-off goods in other markets, such as knock-off designer pants in Europe.
After returning to Facebook page with a heavy and disappointed heart, I clicked on the option to report the ad as a scam. I really did (and do) want it to be true. As if to emphasize its falsehood, I found two more nearly identical offers from two completely different companies right in a row as I continued to scan my Facebook feed.
It's events like this that really damage my trust.
