The hacks
Free shipping at $29 for nail stores
Median nail AOV is $12. Nails are light and cheap to ship ($3-4). Set the threshold at $29. One more set plus a glue closes the gap. 72% of nail buyers stretch for $29.
Hand + toe combo that auto-qualifies for free shipping
Hand set ($12) + toe set ($12) + prep kit ($8) = $32 combo at $29 with free shipping. The combo automatically exceeds the $29 threshold. Tiergain structures hand + toe combos that include free shipping.
Pick-any-3 variety pack that includes free shipping

Buy 2 sets: 12% off. Buy 3: 18% off + free shipping. Buy 5: 22% off + free shipping + free nail art stickers. Free shipping at the 3-set tier is the strongest motivator for nail buyers.
Prep kit add-on that bridges the threshold gap
Cart is $24 (2 sets). Threshold is $29. Show nail prep kit at $8. Total: $32 with free shipping. The prep kit bridges the gap and improves application quality.
Post-purchase upsell with matching toe set
