I noticed that the layout for my product prices are not consistent in my template and trying to figure out what to change.

See here:

http://www.idyemyhair.com/hair-dye/la-riche-directions

the *first* row is how i want it, with the price centered and in bold.
but if you notice, as you scroll down after the first row the prices then align to the left, and not bolded.

can anyone help me figure out what to change in the CSS to correct this? I tried using the firefox web developer toolbar to figure it out but no luck

would appreciate any help, thanks!
