I don't know what a tpc case is, but I'd bet you could find what you need at amazon .
My bad, I meant TPU case.
I want to be able to put the phone with the TPU case on it, into a leather case that I wear on my belt...
Thanks

dancedroidAHA,I'm misunderstood by you.If you need a leather horizontal case,I can recommend one for you.Competitive price i think.My friend ordered it before from Buy Kalaideng Case Skin For Samsung Galaxy S3 [Leather Soft Scrub Ultra Slim Case Skin] For You You can have a look at it.
Here is the link to the case I was referring too. Amazon.com: Premium Horizontal Leather Cover for Samsung Galaxy S3 Slll i9300 (Black): Cell Phones & Accessories
According to the "user review" (these are often fake reviews) it has room for a snap on case, the tpus are generally super slim anyway. It's also $4 and change with free shipping, hope this works mate !
