What $3 off coupon? The only coupons I see from Wall-E are:
$10 off Wall-E Blu-Ray
$5 off Kennedy Space Center
$1 off Light Bulbs
$5 off Disney Books

They don't do a lot but they do still have exclusives. The recently released Tinker bell movie had a few different store exclusives with different toys packaged with it. Also, I remember every pirates movie having a best buy bonus disc exclusive.

Is anyone else here disappointed with the plain silver disc art? Or do some of you have discs with graphics on them like some of the paramount discs have art and some don't?

Sorry for the late reply. I bought the 1 disc of Wall E, so maybe if you bought the 3 disc version you didn't get one. Anyways, here's a scan of my receipt from Walmart, just to show you proof:

Thanks. The only $3 off is through disneyrewards to get a printable coupon

I didn't have to print mine. Mine came as a normal coupon inside WALL E,

My 3-disc didn't have one
