Does it irk you when you want to look at a website that sells stuff, but you have to make an account before you can browse?

I like “Zoolily.” I want to look at their stuff. But there is a big pop up in the middle of the page that demands I make an account first.

Same thing with Deal Dash.

I have not made an account with either at this point.

Is this a wise, or foolish, demand on the part of the web site producers?
