Is 'buy two save X' simpler than percent-off for cosmetics shoppers?

Question

As a cosmetics store owner, I'm trying to optimize my discount strategy and create promotions that truly resonate with my customers. I've been using standard percentage-off discounts, but I'm wondering if a 'buy two, save X' approach might be more compelling for my audience. I want to understand which method drives more conversions, encourages higher average order value, and feels more attractive to cosmetics shoppers who are often looking for value and product variety. What psychological and practical factors make one approach potentially more effective than the other?

The "Rule of 100" applies here: for products under $100, percentage discounts feel larger. But for multi-buy offers, the mental math burden of percentages often overrides the perceived size benefit. "Save $12" requires zero calculation; "Save 15%" requires multiplication that most mobile shoppers won't do.

Dollar Amount Advantages
    
      ✓ Zero mental math required
      ✓ Feels concrete and tangible
      ✓ Easier to communicate in copy
      ✓ Works well for any price point
      ✓ Clear at any item price

Percentage Advantages
    
      ✓ Feels larger on high-ticket items ($100+)
      ✓ Works across different price points automatically
      ✓ Better for promotions shown before item selection
      ✓ Competitive comparison (vs. 30% at competitor)

For cosmetics buyers who frequently multi-purchase for travel sets, gifts, or replenishment, any multi-buy friction reduces conversion. Test "Save $X" vs "Save X%" with your actual audience - results are often product and price-point specific.
