At least in the US, Epson does not sell a sampler of its papers. Here, Red River Paper in Texas has the best customer service, IMO, and reportedly has very good profiles for their products, which cost about half of Epson's. However, even though Epson is not a paper maker (or ink maker), the combination of their paper and inks do provide the longest-lasting prints, based on very high-tech tests done by Aannenberg. (Look for a thread on this forum maybe a week ago.) For anything you sell, this seems important to me. However, a box of Epson Luster takes care of this.
