One of the rare time when discounts starts to combo. Though you might need to some calculations, but the discount is worth it.
First, you have the discount of June running:
-$100-20 for LEGO products
-30% off selected sets.
-60% off 2nd LEGO Movie 2 sets.
Then you have Robinson's sale on going store-wide.
Do take note, that the Robinson discount is not on LEGO but its store-wide. So in simple maths,
its (100-20 or 30%) * (230/300) = 0.8 to 0.7 * 0.7667 = 0.6133 or 0.5357 = 38.7% or 46.3% off
For the 100-20, its best if you buy in multiples of 100 to get maximum discount.
For the 300-70, you can go get other items you need at Robinson to fill up the gap. Baby Products, Lady's stuff etc etc. Keeping the family happy is the way to go to get more LEGO. ;)
