Spanish language learning forums - I would like to buy alpaca clothers, need help

I have alpaca sweaters, I like it a lot, but it already enough old, so I'm looking for a new one.

I have seen many places in Internet with alpaca clothers, but most often I'm not satisfied with the price of sweaters.
I believe that $80-150 (or even more) for one sweater is too much.

Finally I have found one place with cheap alpaca sweaters, they sell wholesale alpaca products.
Well, I'm thinking to make "test purchase" with them, but before I would like to hear your opinion.

Probably you had some experience with the question?
