Not so sure if it is *savings* only, why Costco is so popular !
In our case:
Convenience - most of what we need is *there* .
-- Meat, in our opinion better than anywhere else for a decent cost.
-- No questions asked return policy (Elnina already mentioned that).
---- funny story : Bought a 35 inch flat screen TV.
------------------Left channel audio goes out.
------------------Take the unit back.
------------------Buy a new one (same one)
------------------SURPRISE === 40 dollars cheaper - on sale !!!!
We do NOT buy veggies there. Portions too big for the two of us !
If you need a *hearing aid* --- try Costco !!
But still compare other sources.
We did and chose Costco !
We have the AMEX Costco card. Use that card for almost everything else !
Not just yearly reward check, but also a lot of *benefits* from other places when paid for by that card.
ONLY good if you pay-off monthly balance !!!
Oh btw, we make it a challenge to see how much we can munch of the free samples ....
