can i make an appointment to see a tech specialist regarding a used ipad I purchased through groupon that has the previous owners email still attached? needs to be reset.

It's worth a shot talking to Apple directly, but it's definitely hit or miss as they don't want to really advertise that they technically are able to remove Apple ID Activation Locks from iOS Devices and reset macOS Firmware Locks.

I'm sure you could. If nothing else call and see if they can solve that over the phone. Doesn't hurt to ask.
