Hi Guys, I got a developer to build me a custom wordpress plugin for front end sorting and filtering of SIM only deals. The plugin has a problem and my developer doent know what it is so I am here hoping you guys might be able to spot it.

Essentially, the issue is that in IE8; the plugin takes nearly a whole minute to load all my SIM only deals while in Firefox it takes about 6 or 7 seconds. Once deals are loaded in IE8 plugin performance is also somewhat glitchy - probably because the plugin makes IE8 break into a sweat.

Please look at the plugin in action in IE 8 and view source code and tell me if you see any issues under the bonnet. If I know what the issue is I can get my developer to fix it. Here is my site: Comparisim
