What it is
Stack 2–3 pre-purchase add-on checkboxes on the checkout form. The buyer already has intent, card is out, cognitive load is committed. Each bump solves a distinct concern (speed / protection / completeness). Done right, 20%+ of buyers select at least one.
Why this fits TerraShell specifically
Your PDP converts at 4.9% at $183 AOV — hot buyers. But right now "BONUS Emergency Preparedness Checklist ($29 value)" and "FREE Tactical Whistle ($12 value)" are baked into the bundle as freebies. You're leaving the bumpable value on the table.
The digital-to-printed-checklist upgrade is the sneakiest win in this stack — it costs ~$2 COGS and sells at $9 because you're already promising the PDF as a freebie.
Benchmark data from our library
- Nooro — 3 bumps at checkout. 20%+ of buyers with intent select at least one. Matt Matarano (Checkout Champ) explains the structure: 24:00
- SkinnyFit — stacks 3 bumps on a $5.95 trial — proves the pattern scales down
- Club Early Bird — $14 cold-traffic front-end adds a $2.99 shipping-protection bump = +21% AOV from one bump alone
Proposed TerraShell bump stack
| # | Bump | Price | COGS | Addresses | Expected take |
|---|---|---|---|---|---|
| 1 | Shipping Protection | $6.99 | ~$0 | "Will it arrive safely?" | 25–35% |
| 2 | Printed Field-Laminated Emergency Action Plan | $9 | ~$2 | "I want the real version, not the PDF" | 10–15% |
| 3 | Tactical Fire-Starter + Magnesium Striker | $14 | ~$4 | "Warmth is solved, ignition isn't" | 8–12% |
Blended expected revenue
$3.50–$6 per order. At 1,485 orders in your sample = ~$5k–$9k incremental on identical traffic. At 30,000 orders/year = +$100k–$180k/year from three checkboxes.

Implementation spec
- Checkout engine: Checkout Champ or Zipify OCU. Native Shopify checkout can't handle multiple bumps cleanly.
- Visual layout: stacked cards, each with its own icon, 3–5 word label, 1-line description, and price shown as
+$6.99in green. - Price escalation: low → medium → high, as above.
- Do NOT pre-select. FTC compliance risk (see warning below).
- Position: between quantity tier selection and payment info. Above the fold on mobile ideally.
- Each bump is a separate SKU in Shopify, with its own inventory or "digital/service" classification.
Compliance warning — do not pre-select
Matt Matarano (Checkout Champ): "That's a big no-no with the three-letter agencies. Consumer protection is a real thing. They will tear through it, especially if you start doing some volume." Pre-selected bumps trigger FTC scrutiny. Don't do it. Watch him deliver the warning inline with the Nooro walkthrough:
24:00.
The five principles every bump must satisfy
- Relevance — directly relates to the main product being bought
- Enhances value — practical, not an unrelated upsell
- Addresses objections — resolves a concern the buyer already has
- Logical next step — feels like a natural extension
- Perceived value — framed as high-value relative to price (the PDF→printed upgrade nails this)
Watch-outs
Don't stack more than 3 bumps
Decision fatigue lowers take rates across the board.
Each bump must be differentiated
Three "warranty" variants fail. Speed / Protection / Completeness is the right axis.
Inventory matters
Fire-starters need fulfillment SKU. Shipping protection is a self-insure line-item. Printed checklist needs print-on-demand or batched print workflow.

The 3-bump stack & compliance warning
Expected impact — realistic ranges
Nooro data
20%+ of buyers take at least one bump when given a 3-stack
Blended revenue
$3.50–$6 per order
Current sample
1,485 orders × $5 = ~$7k incremental on the same traffic
Annualized at scale
30k orders/yr × $5 = +$150k/yr from three checkboxes
Margin profile
Bump 1 is ~100% margin; Bumps 2–3 are 70–80% — the blended contribution is high
Next moves
- Confirm checkout stack — are you on native Shopify (switch to Checkout Champ or OCU) or already on a bump-capable platform?
- Source print-on-demand partner for the field-laminated checklist
- Source fire-starter SKU (Bic Magnesium or private label)
- Write & ship all three bump copy blocks; A/B bump order (Speed-Protection-Completeness vs. Completeness-Speed-Protection)
- Set up per-bump take-rate reporting so you can drop losers after 500 orders
