// BOGO = 50% Off?

Buy 1 Get 1 Free on 2 items = 50% off. But only if you want both items! If you only need one, BOGO gives you 0% savings vs the full price of what you actually need.

// B2G1 = 33% Off

Buy 2 Get 1 Free = 33.3% discount (paying for 2 out of 3). Buy 3 Get 1 Free = 25% discount. The more you must buy to get the free one, the smaller the per-unit discount.

// Do You Need It?

The best deal is only a deal if you actually use the product. Buying 4 items at 50% off wastes money if 2 expire or go unused. Calculate cost per item you'll actually consume.

// Retailer Psychology

BOGO feels more rewarding than "50% off" — getting something "free" triggers a stronger dopamine response. Retailers know this. Always do the math before buying.
