OP, just use my system and the wife will stop asking you to go shopping.
Step #1. Eat a dozen hard boiled eggs and a can of beans before leaving the house.
If you fart up the checkout line well enough you wont have to stand in line.
Step #2. As soon as you get there, go to housewares and set all the kitchen timers one minute ahead of each other.
Stand back and watch the associates go nuts. Works best if you hide them in different isles.
Step#3. Go to the health products section and put all the condoms in a separate cart, and follow your wife around loudly saying Baby, I cant wait to get you home.
Works best if she pretends she dosent know you.
Step #4. slip packs of condoms into other peoples carts.
Step #5. Put a womens thong over your head like a mask and jump out in front of people crossing the isle and yell "Stick em up" while making gun fingers and yelling Pew Pew Pew.
The wife hasnt asked me to go shopping in years.
True story.
