LEGO is set to retire well over 100 sets next month, and some of the best sets of the last few years are on the chopping block. One of the best times to buy a LEGO set at a discount is just before it gets officially retired, but that's also when it's most likely to go out of stock. We've already seen the popular Legend of Zelda Great Deku tree disappear at every major retailer well ahead of its retirement date, and several other sets have followed suit.If you're wondering which sets are actually retiring on July 31, I'd recommend checking out this handy guide from Brickset.

Mouse: P.I. For Hire, the stylish first-person shooter dressed up as a 1930s cartoon, has topped 730,000 sales since its launch in April.
