See it on two real parts

Same vehicle, two listings. Shop With Confidence is the checkout total and warranty picture — so you can compare instead of guessing from list price.

Used engine for a Ram 1500

Used engine

2013 Ram 1500

The listing price looked like a bargain. Shop With Confidence adds shipping, core, and the install kit before you choose.

Checkout total was $5,023 — not the $4,030 on the card.

Remanufactured engine for the same Ram 1500

Remanufactured engine

Same VIN · same truck

The reman unit costs more up front. Shop With Confidence puts warranty and due-today next to the used option so you can weigh safety against price with the same numbers.

Same vehicle, two real checkout pictures — pick with eyes open.

Trust states

Three confidence levels

Every listing gets a trust state before you add to cart — so you know when to move forward, when to double-check, and when to talk to a specialist first.

Real checkout total

Not list price alone

Shop With Confidence ranks tier picks by what you actually pay — shipping, core charge, and install kit when they apply. Tax is calculated at checkout.

  • Checkout total today
  • Core charge (refunded when your core is returned)
  • Expected core refund
  • Net total after core refund
  • Estimated delivery
