Hmm, tough luck with the cases so far. I wonder what I would do? Can it be taken in to a local authorized repair place?

- Eat the $25 (will they ding you another $25 for the return?). What's the turn around time and what kind of hassle will that cause?
- Pull the screws out from the inside and cover the holes with a sticker?
- Find some other thing that can be used in place of the foot?

Given you're already on your second case, I might just give up on TP and go with option 2 or 3. Not sure how often I'd personally turn the case on it's side on the ground anyway.
