In the 1970-80’s there was a outdoors writer for the Fort Worth Star Telegram ( Texas, y’all) named Bob Hood.
He wrote in one of his weekly columns how to purchase a new rifle with out the wife knowing.
Volunteer to do the grocery shopping on occasion and write a check for $5.00 over. Put the money in a coffee can and over a period of time, would have enough to buy a rifle he wanted and place it with his others.
*Oh, this rifle? I’ve had it for years, just never got it out.
I worked with a girl who had a taste for expensive purses. She would buy one, then hide it in the closet for 6 months. When she finally started using it, she said her husband would ask if it was new and she would tell him, "No. I've had it for ages."
Lol, it took me years to realize the grocery store cashback option was how my wife funded alot of her discretionary spending...and always had wads of cash in her purse.
