Check Out Buttons Misaligned in IE

Hi all. I need help fixing an IE display issue.

The "price" and "check out buttons" on my product page (http://spicemills.ca/estore/products/) display perfectly in Firefox, Safari and Opera, but do not display well in Internet Explorer. In IE, the price and buttons are skewed to the left and misaligned in the product grid.

I have tried the suggestions posted in the thread at https://premium.wpmudev.org/forums/topic/marketpress-display-problems-in-ie#post-368346 but so far neither has worked.

Any additional assistance would be greatly appreciated. (By the way . . . I am far from a programmer but with a little guidance am comfortable making basic CSS edits.)

Thanks in advance.
Regards
irwin
