KeraFactor is running a 15% off promo code as its headline offer, which applies to your entire purchase on the website. This is the strongest discount available right now and works well for most shoppers.
Small baskets under $200. The 15% off code is your best choice across all price points below the free shipping threshold. On a $50 order, for example, the code takes 15% off for a saving of $7.50 and a final price of $42.50. Even on a smaller $30 purchase, you save $4.50 to pay $25.50.
Baskets from $100 to $200. The 15% code remains the strongest option in this range. On a $150 order, you save $22.50 and pay $127.50 with the code. The alternative 10% off code would save only $15, so the headline code saves an extra $7.50.
Orders over $200. At this spending level, you have two choices. The 15% off code still saves more money on the full price: on a $250 order you save $37.50 and pay $212.50. However, if your basket qualifies for the free shipping offer, compare the free shipping saving against the extra discount the 15% code gives you. If free shipping is worth less than the difference between 15% and 10%, the code wins. For example, at $250 the 15% code saves $37.50 versus 10% saving $25, so you would need free shipping to be worth more than $12.50 to make it worthwhile. Check the KeraFactor website to see which items qualify for the free shipping deal and calculate whether that saving beats the code discount for your order.
Single product focus. If you are buying only the scalp stimulating solution, the 10% off code for that specific product ties with the general 10% off code. Either way, the 15% off code on the full range saves you $5 more on a $100 solution (you save $15 with the 15% code versus $10 with the product specific code).
The 15% code wins on most baskets. Use it unless your order exceeds $200 and free shipping saves you more than the extra 5 percentage points the code provides over the 10% alternatives.
