I've been using Costco branded premium glossy photo paper for the past year, and can recommend it highly. It has the same characteristics as Epson premium glossy (micro-porus, instant dry), and it's so similar that I think Epson might private label Costco's photo paper. I picked up a package of 8.5" by 11"... 125 sheets $18.99. That's $.15/sheet. They had a new offering: 300 sheets of precut 4" by 6" for $13.79. That's less than a nickle a sheet. It's a good deal if you need to make prints for the holidays.
