god and bad workers are every where, I wouldn;t claim Wally world workers are all bad, nor Costco workers are all great!
that said, I have several friends that buy there tires all the time from a few different wally worlds, and have never had any issue's
Hear local wally world will charge 25 bucks per tire to install/mount and balance! ,
if you bring in tires to have installed on your vehicle, plus a fee to get rid of old tires (so a 100 bucks for installing mounting 4 tires PLUS tire disposal if you want will cost more!) a few yrs back they only charged 10 bucks a tire to mount and balance! prices went up!
BUT keep in mind, that many times big chain stores like wally world and Costco , have lower prices on some brands tires, due to the tires they are selling have less thread on them,
as in, many tire makers make the same MODEL tire in different versions, and one will have more thread on it than the identical tire of same make model /size tire
if you go to most ire maker web sites and look up spec's on there tires you will see, how they many times have several tires models with same size, , but different spec's on thread depth!
thus why a tire can be cheaper in one shop as to another, you have to look at spec;'s to know what one there selling!
its mostly on the most common tire models, and brand names that do this!
but it is why some times, large chains have lower costs on tires!
and some other food for thought, buying tires locally from a local tire shop, many times gets you some good free benefits, like free rotation, , free flat repair, and if ever a issue, someone to stand up for you to get a warranty claim on a tire, which is never an easy process without them on your side!
SO< paying a tad more, gets you some rewards and less hassle, being a one stop deal!
and last, HAHA< this time of yr many tire MFG's have special promotion for buying full sets, or two tires,
they do so every fall before winter, to help sell tires!
the discounts can be found on there web sites and a few online tire shops will list them as well!
as an example of a some now
