where can I go to find info on the top five highest grossing E-retail apparel stores of 06.?

Answer 1

There is no data yet for 2006. Typically you can find this data around June/July.

Internet Retailer magazine has a publication called Top 500 Guide http://www.internetretailer.com/top500/ that lists the top ecommerce sites, including apparel stores. This 2006 edition uses 2005 data, so to get the 2006 data you have to wait for the next edition.

That was an excellent answer, thank you!
