Our local Walmart recently got rid of their in-house film processing; it's now send out only. As for panoramic film, I have taken 35mm shot with sprockets in a Holga to my local Walgreens. I just tell them to leave the film intact, and it's never been a problem. The only thing you may want to note is that some stores will roll up that intact film and stuff it in a canister if you don't specify otherwise. They usually do a decent job, otherwise, although you're always taking a chance with a 1-hour "lab".
