Amazon deal: $20 instant rebate on formula

SimilacAmazon's got a new deal on for Similac, Isomil and PediaSure products: spend $119 on selected products, enter the code SIMNOV07 at checkout, and get an instant $20 rebate (and free shipping). As someone who used to buy PediaSure (at about $2 a bottle!) I know how important any savings can be.

I was never a regular formula buyer (and even then it was years ago), so can anyone confirm if these are good prices? I know you can get formula on sale, and there's always Costco, but I also know it's nice to avoid a frantic trip to the store.

Unfortunately you can't use this rebate in conjunction with Subscribe & Save. (The Amazon page lists all the restrictions, because there are always restrictions, right?)
