Need to remove the price in the drop down and only display label

First of all everything works great except for one minor detail.

Need to remove the the price in the quantity drop down when integrated with WooCommerce.

It displays "50 +$257.50" and I need it to be just "50".

My client is a boutique design agency specializing in well designed wedding invitations. They required an e-commerce solution to allow customers to select a design then choose options/add-ons (quantity, color, gender options, additional info cards and mailing lists). Each with variable drop down selections.

Was able to achieve everything with this setup

-Gravity Forms (1.6.3.1)
-WooCommerce (1.4.4)
-WooCommerce - Gravity Forms Product Add-Ons (1.3.1)
-WP (3.3.1)

Here's what the form looks like on the front end:

Here's the exported XML:

I had to create unique Gravity Forms for each product and then associate it with its respective WooCommerce product.

They wanted to sell in only sets of 25 so I "enable values" which worked.

In this case, I set the WooCommerce base price for $257.50 and the Gravity Form price $0.
For the Quantity:

Label 25, Value 25, Price $0
Label 50, Value 50, Price $257.50
...and so forth

Shopping cart and data-wise, everything works. I just need to remove all the the prices in the drop down selections on the front-end:

ie..."50 +$257.50" instead of "50".

<field id="10" size="medium" type="option" inputType="select" productField="14" enablePrice="1" enableEnhancedUI="1" enableChoiceValue="1">
        <description><![CDATA[(<strong>PRICE</strong>: $257.50 per set of 25)]]></description>
        <label><![CDATA[Quantity]]></label>
        <choices>
          <choice>
            <text><![CDATA[25]]></text>
            <value><![CDATA[25]]></value>
            <price><![CDATA[$0.00]]></price>
          </choice>
          <choice>
            <text><![CDATA[50]]></text>
            <value><![CDATA[50]]></value>
            <price><![CDATA[$257.50]]></price>
          </choice>

Side note:
They also requested the customer only pay a 50% deposit + applicable taxes (this was achieved within WooCommerce and had nothing to do with Gravity Forms)
