I always use the time of year and say that my mom is having people over next week and while I was here, she wanted me to check the price of <whatever the item>. I need to know how many packages she needs to feed 20 people for Christmas, Easter, Father's Day, etc. If no good holiday, then I use a birthday.
I like using my mom as then they won't think it is weird that I don't get the item as I like to get items I need anyway.
Shopping across Indiana but mostly around Indianapolis.
