Ok well obviously the person who emailed a response to you last did not look at your profile at the bottom.....HELLO.... 2 kids live in Keller. Wonder if she has any clue how far Keller and Irving are from one another? Anyhow, Sorry but I had to put that in here!
I would try to call a courrier service? spelling>? I am sure if there is a Tom Thumb in the area, you can call the manager of the store give him the story and then see if you or she can call in her order and credit card info and then have the courrier service pick it up and deliver it to her house. It would be less expensive than a personal shopper or assistant, unless she needs other things done for her like library, driving service or dry cleaning pick up? Good Luck
