I've spent the morning (Friday off, here) extracting and copying data for most of the sets we're interested in. I have image files for all the currently available exclusives, plus many other sets. Just an FYI. There's so much to do here, lots of info to digest.
Here's some early data. The best selling sets were the Helicarrier (700 units is 7 days, steady 100 units/day), Slave 1 (no surprise) and T1 (big surprise, data below). Other robust sales were of all the modulars (roughly 250 units/week for all), Tower Bridge (160 units/week), TOO (90 units/week). T1 was killer, (350 units/week till sold out); the mini cooper not so much. Sydney Opera house moved a steady 40 units/week.
The trains were slow movers, and sold in lockstep at about 10 units/week (roughly same numbers of sale for 60050, 60051, and 60052 and the track packs). Speed Champions is interesting. In the EU, the Porsche was the best seller (almost 200 units/week, and the small cars all sold about equally. For every Ferrari Truck sold, they sold 3 sets of the small cars. There's some dogs with few sales, Fairground Mixer, Arctic Base Camp (10 units/week) and Simpson's House. Mindstorms EV3 was completely dead. 42009 moved a steady 60 units/week, while the 42030 Volvo Loader was slower at 30 units/week.
In Star Wars, Slave 1 is the champ, which moved 350 units in 4 days to sell out. Sandcrawler was a good mover, 100 units/week, and Death Star which moved 80 units/week. Ewok Village did 50 units/week. Red Five moved at 90 units/week until sold out, twice.
Another observation, double VIP sales period had little effect on the data. Basically all these sets had inventory levels move at the same rate pre- and during double VIP.
This is just a snapshot, more analysis to come...
