so I have a bit of strange situation now:

I had originally preordered this at $29.99 but realized I wouldnt really use the 3D or digital copy, so I cancelled my preorder and instead preordered the 2 disc BD at the Disney Store for $24.99+shipping, along with a set of lithographs and supposedly a $10 off coupon for an online purchase there that I would receive at release. Well no email yet but my copy got here last night. However, I'd really rather just pay $19.99 for the BD on Amazon, so should I plan on returning the Disney order (still unopened) or hope the coupon comes? Appreciate some advice on this one.
