Buy 2 toys and get 3rd free. So effectively 33% off LEGO (if same priced item). In-store only and not conjunction with any other offers. Offers not available at Hurstville Myer.
*Lowest priced item free and purchased in one transaction. Excludes wheel & outdoor toys, Disney Infinity, nursery & [app]cessories
OP: 33% off doesn't quite mean the same thing as buy 2, get 1 free. Someone would be very disappointed if they saw the heading of this post only, and walked into Myer expecting to buy one or two items at 33% off. I suggest the heading be reworded.
EDIT: It's also only a best case of 33% off, where all items are priced the same. There's a good chance the total saving would be less than 33%.
