Starter kit configurator, razor + blades + cream + balm bundle. Build pattern?

The starter kit is the conversion lever for first-purchase. Harry’s built the model: $5 trial set (razor + blade + cream + travel cover) auto-enrolls into the monthly sub. Dollar Shave Club: $5 starter set with the “Humble Twig” razor.

Build pattern on Magento:

• Configurable + bundle product hybrid. Top-level bundle product, customer selects handle (chrome / black / wood) → 2 blade refills (4-blade or 5-blade) → shave cream (sensitive / standard / menthol) → post-shave balm (alcohol-free / standard) → optional brush. Tiered bundle pricing in Magento native.
• $25, $45 bundle price, ~30% off vs à la carte. Loss-leader for the first-purchase, sub-revenue is the real margin.
• Auto-enrol into matching subscription on checkout. Checkbox pre-checked “Auto-replenish every 4 / 6 / 8 weeks”. Some brands force the enrollment (Harry’s does this on the $5 trial); others give an opt-out. Forced enrollment with prominent cancel-anytime copy converts ~25% better but generates more complaints.
• Skip-the-line acquisition discount, first-time customer sees $35 bundle, returning customer sees $45. Magento sales rule by customer-segment.

Bundle conversion vs single-razor PDP: 35-50% higher in my data. Bundle AOV: $32 vs $14 on single-razor. Auto-enrol-to-sub conversion: ~60% of bundle buyers if forced, ~38% if opt-out, ~22% if opt-in.
