Create CSS from PSD to work in all browsers.
Middle Offer boxes must be contained in one table per offer, at same height, as they will be integrated dynamically with a store and need to repeat on a loop. Please do not put Pricing and Buy Buttons for 2 different offers next to each other in . I will show you what I had to do with your last code to sort this out. All grey columns on left and right must be able to grown downwards as content length will change.
Please ensure good commenting and structure is used on CSS.
