Update 2: Sold out now.
Update: Max discount for the coupon code is $30. Note that the code also works on other items that Toys R Us eBay is selling.
Forum member kevin7215 notifies us that Toys R Us eBay currently has the LEGO Ninjago Board Game on sale for $11.5 (reg.$24.99). Savings work out to be 54% off. Best of all, this item ships for free and there is also a 15% off coupon that is good for today only (brings the price down to $9.78). Coupon code is CTOYSRUS.
For a $9.78 item, I’m pretty sure that they don’t make any money from this with free shipping and the high eBay fees (even with power seller status).
