T.F.
My mom loves her gardening. About 6 yrs ago I sent a rose bush to her thru the local florist and to this day she tells me how pretty it is and how much she lives it year to year.
One year I sent a towel warmer. She and my stepdad have enjoyed this perk. A nice hit towel as they got out of shower or bath.
They like cooking and I send steaks, desserts, etc for them as well.
Postage stamps and cards are good.
I called the local gas company and had my dad's tank filled up for winter.
Anything made by my daughter is a hit.
Hope that helps a bit!!
