Affiliate Marketing Secrets

I have been searching for a reliable asian fashion wholesaler and found yesstyle and fashion4us.com
I really like yesstyle but it is so expensive. I also like fashion4us.com but I know shipping will be expensive and I haven’t read too many reviews for them.
Between the two sites, which do you suggest I buy from? I live in the US.
Also, are they the same site or affiliates or something? Their website layout looks really similar. The way they list their brands, the recently view tab, how they list their colors, etc. JW.
