I emailed the store, leaving my phone number at work. The owner called me abotu 10 minutes later (total aside, but I knew it was him because he actually pronounced my last name correctly. I swear no one outside of a 50 mile area in MN ever does, so it was exciting.), and I explained to him that the gift had to be anonymous. My parents refuse to understand the meaning of the word gift and would have tried to pay me back.

One credit card transaction later, and my parents are getting a reasonable amount of gift certificates.
