How O’Reilly Auto Parts pricing actually works
The loaner tool programme lends specialist tools against a fully refunded deposit, which is worth far more than any coupon if you need a puller or compressor once. Battery and part core charges are refunded when you return the old unit.
Loaner tools are lent against a fully refunded deposit. The promo code field is at checkout with the order summary. Core charges and loaner deposits are refunded separately on return.
- 1
Use the loaner tool programme
Specialist tools are lent against a deposit that is refunded when the tool comes back.
- 2
Return the old part for the core charge
Batteries and some components carry a core charge refunded on returning the old unit.
- 3
Check in-store pickup for online orders
Collecting avoids shipping and gets the part the same day.
- 4
Check the warranty tier on the part
Parts are sold at several warranty levels, which matters more than the price difference.
