While I don't have a ton to add to what has already been said, I have nothing but pleasant things to say about this store. It is exactly what it looks like, and doesn't try to pretend to be anything else.
If you are expecting a fancy store, with fancy displays, and fancier prices you might be disappointed. If you are looking for any sort of southwestern souvenir type option, especially en masse, at incredibly low prices; this is your jam.
I have used this store to find some fun presents, I have taken guests here so they could stock up on souvenirs, and most importantly this store has been clutch when trying to come up with goodie bags for themed events or for out of town visitors at my job. They have a very wide selection from dream catchers to sugar skulls and range in authentic options all the way to standard southwestern kitsch, native to latin, pricey baubles to complete tchotchke heaven. It's like pick your own adventure every time I step in there.
The staff has always been more than helpful in this family run business. Pro tip: there are baskets under some of the blanket clad tables by the register if you are buying 100 mini sombreros like someone I know. They take cash and card and often have more of something in the back if you don't see enough or know a viable alternative option when in doubt.
