Use regex or something else to capture website data

I'm trying to use python and regex to pull the price in the example website below but am not getting any results.

How can I best capture the price (I don't care about the cents, just the dollar amount)?

http://www.walmart.com/store/2516/search?dept=4044&dept_name=Home&query=43888060

Relevant HTML:

<div class="price-display csTile-price">
       <span class="sup">$</span>
       299
       <span class="currency-delimiter">.</span>
       <span class="sup">00</span>
</div>

What would the regex be to capture the "299" or is the an easier route to get this? Thanks!
