You can buy them separately on preorder at $16.99 ea (free shipping if you buy both, supersaver). Do you think they'll be cheaper in store with a coupon? I'm considering pre-ordering them just to be done with it. The release date says 5/11.
ETA: I just noticed this on the Mar 23 release DVD/blu ray combo packs...

If you click for 'all participating titles' it says that the Toy Story blu ray combo pack AND the TS2 combo pack are both participating. They're $24.99 each, so $49.98 - $8.50 free ticket in each. Hmmmm, maybe I'll just preorder the blu ray ones and get them in March instead.
Oh, wait! If you buy both March release blu ray combo packs, you get an additional $10 off. So $39.98 for BOTH...and an $8.50 ticket in EACH. I'm ordering!
