I generally shop by myself. My elderly Mom and I used to shop together but she has a man-friend now so she doesn't go shopping with me anymore (Good for Her!!!

).
My husband doesn't shop with me because he is the type to just throw stuff in the carriage that looks good to him. LOL. He's like a kid in a candy store. He's so cute and I don't have the heart to say "It's not on the list, honey". LOL.
I also find that when I shop by myself it doesn't take as long to shop. So I actually end up saving time and money when I go it alone.
