I would think something like:
<option value="1">16 oz. Hair Moisturizer</option>
<option value="2">32 oz Hair Moisturizer</option>
<option value="3">Gallon Hair Moisturizer</option>
<option value="4">5 Gallon Hair Moisturizer</option>
Then in your database you have a table of options with
ID, Name, Price
you can then filter a recordset with the submitted list value and return the associated option name and price from a single list. Then bind those fields in the cart from the recordset you have created.
