I got $57.39 off my order using the DISNEYTREAT coupon, for 10% off.
If you had broken your order into three separate orders:
Lamp: $229 (+tax/shipping)
HB/Big Fig: $175 (+tax/shipping)
Organ figure/Sconce: $169.90 (+tax/shipping)
You would have gotten $45 off of each order, or saved $135 total. (adding in the extra shipping which might have run another $25, you probably could have saved about $110 instead of $57).
I placed six separate orders today for the lamp, big fig, 2 sconces, pewter figure set, 4 tapestries, and the HK box. I saved a whopping $270 ($45 x 6), plus I got 6 free NBX pin sets and free shipping on everything!!
