Well yes its an old, but somewhat popular thread.
So even though it wasnt Ranger related, I had a great time at Wal-Mart(even though I know they are EVIL CORPORATE MONSTERS, that will further separate the classes...but I digress...I like "inexpensive" stuff too.
Now granted this was 5 or so years ago, I brought in my own used tires, and my used ImpalaSS rims and had them installed and balanced, then very politely asked if they could then put the wheels on my 94 Caprice wagon...they did say they wouldnt fit at first(apparently someone tried to put the same style rims on an older wagon...no they dont fit). But after reassuring them that they would fit, they were very happy to put them on my car for nothing... So yeah...all I paid for was 4 mount and balance, 4 tire disposal...and that was it. Granted I talked to the mechanics first, before I went to the counter...(not my first rodeo there..lol), but yeah..that worked out fine.
Now of course there was the time they under filled my wife's autotrans in her Lumina...some things...they just dont get to do. (She was trying to do maintenance on her own...for that I give her credit....but taking it to WalWart..well credit taken back...lol). Luckily we didnt live far away and I figured out what they did, fixed it then got a FULL refund.....the trans lasted for several more years. We sold it when it started to slip some...and yes the buyer was fully informed of what all was wrong with the car....(I had already replaced the LIM that always went bad on them).
All and all...like any garage...even ones you KNOW, always double check what they do, everyone makes mistakes...
But if a "counter" person argues with me...then yeah...either they do what I want, or I leave. ...and I will leave with ALL my money...even if they TRY to scam me...yes that has happened too...lol.
