This is what is happening right now at their site, Black Friday pop-ups which you can close, but everytime you turn the page browsing their site that stuff spawns again. Unceasingly. Bang… :| bad.
And let me tell you, many people goes to your site looking for interesting deals. In the old site from one or two years ago I could see the china warehouse price by default, letting me see the bulk pricing, shipping options and also letting me select other warehouses. It was less bloated and better. Now I have to keep looking for the china warehouse deal, and the site is comparatively crippled. Please understand some people doesn't likes advertising at all, especially if it gets in the @#$%ing way.
By the way, your site search engine sucks bollocks.
Take care.
Cheers :-)
