I think is funny that anyone post RA discount...
Getting a code is so easy and push the 5% thru all kinds of email, web search, and even snail mail.
Most times 5% is very little to nothing because Shipping is a lot more and basically cancels that and more.
TFS has discounts too and many things are/were exempt for club discount codes.
RA has discontinued items that are cheap, say $1 and less, only get a ship charge for $8-10. But main inventory is $2-5 and ship change drops noticeably.
And Trying to bundle several parts often won't help.
Many part I get local and often cheaper after RA shipping is added.
If I order AZ and some others online, many have a big discount and shipping is free after X amount. Brake rotors are heavy Discounts and free shipping often beats RA total price.
If something is wrong or have a core then can return to local store. Advance and some others to this.
