Check shopping for HSA checks

I think I'm down to about 5 checks left on my HSA checks and need to start thinking about reordering. I know I can go directly through the bank, but I was not at all impressed with their service last time and I know from experience that ordering directly from the bank is much more expensive. I'd love to be able to use an SR merchant, but I didn't see anything about HSA's listed on the FAQs sections of Checks Unlimitted or 4Checks. I think there's just a few extra boxes they need to print.

Has anybody with a Health Savings Account ever done a check reorder online? Do they know it's an HSA account and to include the few extra items on the checks/deposit slips? It's really more the deposit slips that are the issue here, as I am the one who makes the contributions and claims the deduction.

Thanks!
