BOGO Math

We all know that coupon math is a special math!  It’s one where 2 + 2 might not equal 4.

BOGO sales and BOGO coupons seem to be the most confusing for people so here is a little primer with a graphic to help explain it even better.

The drug stores and grocery stores run BOGO (B1G1) sales differently.  At drug stores in a BOGO sale- 1 item rings up full price the other rings up $0.00. At the grocery stores each item rings up 1/2 price. So that has an effect on how BOGO coupons work at each store.

BOGO Sale + BOGO Coupon

Drug Stores: The sale gives you 1 free and the coupon gives you 1 free= 2 Free
Grocery Stores: The sale gives you 1/2 off each and the coupon gives you 1 Free= 1 1/2 free , Buy 1/2

BOGO Sale + B2G1 Free Coupon

Drug Stores: You will need to buy 4: The Sale gives you 2 Free and the Coupon Gives you 1 Free= 3 Free, Buy 1
Grocery Stores: You will only need to buy 3.  The Sale gives you 1 free, the Coupon Gives you 1 Free= 2 Free, Buy 1

*This is assuming the coupons do not “auto deduct” which means take off the maximum value of the coupon regardless of the sale price.
