Good Evening everyone, long time collector and seller of LEGO. I live in Florida and do it as a hobby, have had some of the greatest sets of all time in terms of ROI (Ferris Wheel, Taj Mahal, and numerous smaller sets.) So I know alot about the beauty of quick exponential growth through LEGO investing. I think this is a great site to assist others in LEGO investing as we are a small enough community that we can help each other without flooding the market. I intend to advise of when I find any set on clearance at Wal-Mart (using the paid + app now.) Currently this is what I have found:
Harry Potter Great Hall 75954 $25 (long sold out)
Fire Dragon 71753 $25
Water Dragon 71754 $35
Batman Cowl 76182 $25
Venom 76187 $15 and $30
Scout Trooper 75305 $25
HP Forbidden Forest 75967 $13
Mario Starter Course 71360 $36 (this hasn't been at this price for a long time in my area.)
Mario Chain Chomp 71381 $8
Mario Desert Pokey 71363 $7
Mario Whomps 71364 $7
Mario Boomer Bill 71366 $10-$13
Lego Spiderman and Mysterio 76174 $17
These are the main sets, there are a few more random ones that have been store specific, but I recommend scanning all the Marios, Ninjago, Cheap Star Wars, and Harry Potter sets.
