You can get them from buckle mainly.
it depends on what you consider expensive. rue religions are always gonna be on the pricey side. Any designer jeans will be.
Miss mes are also great desinger jeans too.

Also zappos has designer stuff for really great prices, with free shipping and alot to choose from. Norstrom rack has alot of stuff too. You could try there.
eBay, or don't be cheap and buy them from the actual store?
I got mine pretty cheap I payed 172 for them and they were some of the cheaper ones,
Rhinestoned ones are always going to be more expensive..
