Can I order food on-line pay for it with my food stamps and have it picked up by a family member

EBT cards do not have experation dates or a CVC 3 or 4 digit code on the back of them so no they can not be used to order anything online.

no

You have to go in to pay EBT period.

Nope

I do not believe that can be done

No I'm sorry they don't do it that way.

Their online service seems to require in-store payment.
