My husband and I are elderly and should stay home. May we send our daughter to gather supplies for us with our card?

Not sure how accommodating they will be (in usually scenario deffinatley not) I would suggest calling ahead of time explaining the situation prior to heading down.

U can but if you need toilet paper and paper towels no promising there will be toilet paper but paper towels possible I would go asap

And

If she is not on the account must likely she won't be able to.

If you are spending more than $250 just order online and have them delivered to you.
