S> Sure I am a member, but did'nt never ever bought a single tire there.
S> The clerk told me it's a "service" they offer to ALL their members.
Excellent. I will enquire the next time I am there. On this Nitrogen business,
if it is costing me nothing extra then I am ahead because I don't believe
that it is any worse than air, and if anything it is better. Even if it costs
me a little extra but keeps the tires are the right pressure longer then
that is worth it also, since my time is money.
S> So, as Matt said, it's not "free" because I pais my member card. But
S> it's free, because I didn't pay for this specific service.
If you want to split hairs, it may not be free depending on how much you
shop at Costco, but if you shop at Costco often you have already paid off
your membership card fee so it is free.
