My mother did call me once rather early in the morning (but way after I wake up regularly) to let me know that grape juice was "buy one, get one free" at Publix. But she knows it is my favorite beverage and I drink it a lot. And it is my mother. And I am over 30. And I do not always check the supermarket shoppers, since I do not receive a hard copy newspaper at home.
Some new person I just went on one date with? It would come across as awkward- unless I told him that I like, say, peaches, and he did send me ONE text to tell me "Hey, peaches are on sale at Winn-Dixie- they look delicious".
Again, it is romantic if you like him, annoying if you dislike him, and awkward at worst if you are ambivalent towards him.
